What is Breast Ultrasound and uses of the procedure?

Breast ultrasound is an imaging technique mainly used to screen for tumors and other breast abnormalities. High-frequency waves are used in ultrasound process to produce elaborate images of the inside of the breasts. As x-rays and CT scans use ultra waves but ultrasounds don’t use radiation and are considered to be a safe medical method for pregnant women and breastfeeding mothers. This procedure requires little to no special preparation.

Doppler techniques are used by a sonographer or by the physician during breast ultrasound test to evaluate the blood flow or lack of flow in any breast mass. Some common uses of this procedure are as under:

·       Determining the nature of a breast abnormality–The primary use of breast ultrasound today is to help diagnose breast abnormalities detected by a physician during a physical exam and to characterize potential abnormalities seen on mammography or breast magnetic resonance imaging (MRI).

·       Supplemental breast cancer screening -Mammography is the only screening tool for breast cancer which is known to decrease deaths caused by breast cancer through early detection. Many studies have shown that ultrasound and magnetic resonance imaging (MRI) can help extend mammography by detecting breast cancers because in mammography they are not visible at times.

·       Ultrasound-guided breast biopsy - A physician may choose to perform an ultrasound-guided biopsy if the reports of ultrasound examination disclose a suspicious breast abnormality. Because ultrasound provides real-time images, it is often used to guide biopsy procedures.

The images produced by a breast ultrasound don’t mean that you have breast cancer. Most breast lumps are kind. 

Dense breast tissue : What are the causes of dense breast tissue accumulation?

Body mass index: Studies reveal that women having a low body mass index than the advised limit, have a higher chance of facing breast cancer due to dense breast tissues. Clearly, this is due to the absence of body fat.

2.     Hormone therapy: Menopause is an inevitable phase in every women’s life. It denotes the end of the cycle of periods which takes place every month. This causes a lot of hormonal changes into the body of the woman. Hormone therapies can help in this matter but can give rise to dense breast tissues.

3.     Age: A young age gives a good physical appearance to everyone. In case of women, it denotes properly working muscles and strong bones. But the ageing process can be a cause of concern as younger women have denser tissues in comparison to aged women. This phase makes it difficult for catching the early signs of the disease also.

What is the biggest problem?

The aforementioned fact that dense tissues will make analysis difficult is the biggest challenge in front of experts right now. Over the years, multiple tests have failed to detect signs of breast cancer due to dense breast tissues, because it is tough to penetrate the dense tissues are produce the required result for a proper diagnosis. Mammogram has been ineffective multiple times in this case. As it is better for the disease to be caught early and treated effectively, advancements are being made to solve this problem.

How tomosynthesis is different from mammography

Tomosynthesis is considered a more advanced and detailed imaging technique than a mammogram in the following ways:

·       With the benefits of 3-dimensional images, tomosynthesis can look at multiple layers of the breast. This allows this method to fill in the gaps or limitations that traditional mammograms have since a mammogram only captures a 2-D image.

·       It can detect breast cancer before many women ever start to have any symptoms.

·       The 3-D imaging of a tomosynthesis allows your doctor to see small lesions (damage or change in the tissue of an organism) and other signs of breast cancer earlier than a traditional mammogram.

·       Tomosynthesis is more accurate than mammograms and also helps to minimize false positives that mammograms can give.

·       In terms of comfort, tomosynthesis does not require to compress the breast like they would be during traditional mammography.

Some positive aspects of using tomosynthesis

1.     It gives us better results and screening for dense breasts.

2.     Helps in detecting breast cancer at an early stage.

3.     Less suffering since there is no breast compression.

4.     Detection of breast cancer in women with no symptom.

The procedure for a tomosynthesis is very similar to that of a mammogram. Both tomosynthesis and mammogram use the same imaging machine. However, the type of images it takes is different because not all mammogram machines are able to take tomosynthesis images. In the case of the mammogram, two x-rays are taken of each breast. Tomosynthesis is taking multiple images of the breast. Overall, the time duration taken by tomosynthesis procedure is 15 minutes. Mammograms and tomosynthesis exams can be recorded digitally and stored electronically on computers. These x-ray exams are fast and easy which consumes less time and the equipment used in these x-rays are normally less expensive in the market. 

Tomosynthesis or 3D mammography:

Tomosynthesis is a modern form of dense breast tissue analysis, which can also be considered as an advanced form of mammography. The method employs low amounts of x-rays to catch the signs of cancer at an early stage, because it is easier to treat it during the starting phases. The fact that the two techniques- tomosynthesis and mammography are both used to detect breast cancer makes them similar. Also, both use breast imaging techniques for the cause. Tomosynthesis for breast is better known as 3D mammogram and digital breast tomosynthesis (DBT) as it creates high-quality photos of the target area with the help of computer reconstructions.  The three-dimensional images help in having a proper look and determining the next step of treatment. Although mammography is considered to be the most dependable method to analysis for breast cancer, it can overlook some details which might turn out to be important for the case.

Mammogram:

In simple words, a mammogram is an x-ray report of the concerned breast. In this, a specific machine for this purpose is employed. The doses of x-rays are quite low and so is the radiation. What makes things difficult is that the rays do not penetrate easily, which is why the breast has to be compressed with the help of two plates for getting better results.

An important point to note is that the chance of any problem arising due to the radiation is minimalistic and insignificant. Another imperative fact is that just one report does not claim any women to be free of the risk of cancer, as the mammogram can only show if the area is worth consideration for any suspicion or not. If the mammogram detects signs of cancer, but there is no cancer in reality, the result is said to be a false positive.

Breast ultrasound: What do you mean by breast ultrasound?

This is a method, with the help of which one can effectively screen the targeted area of concern. High-quality images can be produced for analysis, which is why doctors recommend it for evaluating the dense breast condition in the patient. Thanks to modern technology, it is now possible to perform ultrasound without the help of mammography, and this is an incredible breakthrough for the benefit of mankind. The reason is that it was very challenging to analyze the cases of younger women, as mammography is not successful in penetrating through the dense tissues.

If the doctor wants, they can decide to perform a breast ultrasound as a part of diagnosis. A small needle is needed for this process, and it is almost painless. Another striking feature is that it takes very less time for the procedure to be complete.

Necessary facts:

1.     Women with having dense breast tissue accumulation must undergo multiple analysis. The difficulty of determining the right tissue compels the expert to repeat the process until the distinction between the tissues is apparent.

2.     Although breast ultrasound is very dependable, it is not definite at all times. There have been some cases when the condition could not be detected, but this does not downplays the utility of the method.

Needless to say, the benefits of breast ultrasound dominate its disadvantages. It is undoubtedly an important future projects and with continuous developments will become an important part of dense breast diagnosis.

3D mammography

This is one of the modern methods, which helps in the analysis of dense breast cancer. It is mostly used in cases of breast cancer, where analyzing the tissue is imperative for treatment. There are a lot of alternatives to this method, namely traditional mammography, automated whole breast ultrasound, and breast magnetic resonance. Each of them are significant in the following ways:

1.     Conventional: Doctors consider it as one of the most dependable methods to detect breast cancer. This is because it is deft in catching the early signs of the disease, which help in preventing the case altogether. It helps in getting high-quality images of the tissue area and analyzing the next step to be taken. It is a no-brainer that catching the early signs will help in getting diagnosed properly, and cheaply. The best thing though, is that it allows other steps to be taken if it fails.

2.     3-dimensional: Also known as tomosynthesis, it is a proud result of years of medical advancements. 3D mammography screens the concerned area efficiently, without the hassle of the shadows of nearby organs or tissues. This helps the radiologists in getting a distortion-free image.

3.     Automated whole breast ultrasound: The accuracy of this technique makes it the most demanded in the world at the moment. Younger females are difficult to analyze for dense breast condition and this poses a challenge. But this method solves all the problems and helps in seeing through the organs and tissues to properly view the targeted area. It takes less than twelve minutes for the process to complete and is complete painless.

4.     Breast MRI: Uses magnets to create images of the area, and is one of the most prevalent methods known.

Tomosynthesis v/s mammography: What is the difference?

Tomosynthesis is considered to be more advanced than its counterpart as it provides more high-resolution images. Other reasons include:

·       Tomosynthesis looks are more than two layers of the tissue in a 3-dimensional photo. This papers the cracks of the 2-dimensional images obtained by mammograms which miss a lot of details due to their limitations.

·       Detection of the early signs of a serious disease regarding the breast is possible. It helps in early treatment and the prevention of the condition.

·       The 3-D modelling of the area will help in detecting lesions and many other signs, which a typical mammogram result overlooks.

·       All the false positives which a mammogram result produces can be confirmed with the help of tomosynthesis. This proves the accuracy of the method in providing the right answers.

·       The process of tomography does not require the breast to be compressed, like in a conventional mammography.

Some advantages of tomosynthesis:

1.     Far better results and analysis for dense tissues in a breast

2.     Timely detection of a health problem before it becomes serious, to avoid complicated treatments

3.     More comfort, as the compression of the breast is avoided

4.     Even without symptoms, breast cancer can be detected with the help of this method.

The similarities between a tomosynthesis and a mammogram come down to the process and the machinery involved. The tools used are the same in both techniques and the process is more or less the same. The difference is apparent from the result, which is more helpful images thanks to tomosynthesis. The whole process takes only fifteen minutes and can be recorded and stored digitally on a computer.
