image & CT-Guided Biopsies
A biopsy is defined as the removal of tissue from a suspicious growth that will then be tested for disease. In some biopsies, samples can be removed with a small needle. On the other hand, some growths or lumps may need to be surgically removed. Some biopsies can be performed with guidance from an MRI, ultrasound, or other medical imaging tests to locate exactly where the suspicious growth is. Some common biopsies include CT-guided lung biopsy, CT-guided liver biopsy, and fine needle aspiration of the thyroid.
CT-Guided Lung Biopsy
A CT-guided lung biopsy uses real-time images produced by CAT scan technology to aid in locating and extracting samples from masses or nodules in your lung tissue. During a CT-guided lung biopsy, a radiologist will insert a thin needle into your lung to collect tissue samples. These samples will then be evaluated under a microscope by a pathologist to determine if the mass or nodule is benign (noncancerous) or malignant (cancerous).
CT-guided Liver Biopsy
A CT guided biopsy of the liver uses real time images produced by CAT scan technology to aid in finding and extracting samples from a mass or nodule in your liver. During a CT guided liver biopsy, a radiologist will insert a thin needle into the liver to collect a sample of cells from the mass or nodule in question. The collected sample will then be tested under a microscope to determine if it is benign or malignant.
Fine Needle Aspiration of the Thyroid
Your doctor may recommend a fine need aspiration of your thyroid to evaluate a discovered mass or lump in the thyroid gland. During an FNA of the thyroid, a radiologist will insert a thin hollow needle directly into the lump (nodule) to extract cells. This process may be repeated and all nodules larger than 1 centimeter in diameter will be sampled. The collected cells will then be evaluated under a microscope to determine if they are benign or cancerous.
A biopsy of the breast removes a sample of breast tissue that is evaluated under a microscope to check for breast cancer. A breast biopsy is usually done to check a lump that was found during a breast examination or a suspicious area found on a mammogram, breast ultrasound, or breast MRI. Some breast biopsies can be performed using a small needle, while other breast biopsies may be completed through surgery. Common breast biopsies include fine needle aspiration of the breast, core breast biopsy, ultrasound-guided breast biopsy, and surgical breast biopsy.
Fine Needle Aspiration of the Breast
A fine needle aspiration of the breast (FNAB) is a diagnostic biopsy used to evaluate superficial lumps or masses in your breast tissue. During an FNAB, a radiologist inserts a thin, hollow needle into the breast mass to withdraw (aspirate) a sample of cells. These cells are then examined under a microscope to determine if the mass is benign or malignant (cancerous). The needle used for FNAB is thinner than the ones used for blood tests, and a local anesthetic is used on the biopsy area to minimize discomfort.
Core Needle Breast Biopsy
A core needle biopsy of the breast is a diagnostic biopsy used to evaluate lumps or masses in your breast tissue. Although a core biopsy is similar to a fine need aspiration biopsy, a larger hollow needle is used to collect small cylinders (cores) of tissue from the area of the breast in question. Three to six cylinders of tissue are usually withdrawn and are then studied under a microscope to determine if the mass is benign or malignant (cancerous).
Ultrasound-Guided Breast Biopsy
Ultrasound technology can help our radiologists assess a lump or tumor within the breast. A breast biopsy using ultrasound technology uses a vacuum-assisted device to take a small sample of tissue to be tested. Performed on an out-patient basis, an ultrasound-guided breast biopsy can help you avoid any surgery that is not necessary. The sample that is collected during this breast biopsy will be viewed under a microscope to check for any abnormalities.
Surgical Breast Biopsy
Surgical breast biopsies include an incisional breast biopsy and an excisional breast biopsy. An incisional breast biopsy is when a small sample or part of a breast lump is removed for testing. During an excisional breast biopsy, an entire breast lump or growth is removed through surgery for testing. In some cases of excisional breast biopsy, stitches may be required to properly close the biopsy incision. Additionally, if a larger lump is removed from the breast, there is a possibility that the shape and appearance of your breast may slightly change.
