Sentinel Lymph Node Biopsy
What Happens When the Sentinel Node Is Found To Be Cancerous? After the surgeon removes the sentinel node(s), a pathologist will perform a preliminary examination of the nodes to determine whether they contain cancer cells.
Benefits and Risks of Breast Biopsy
Benefits of Breast Biopsy The benefit of a breast biopsy is that the patient should receive a definitive diagnosis of whether she (or he) has breast cancer or whether the breast abnormality in question is benign (non-cancerous).
Benefits and Risks of Breast Biopsy
Risks of percutaneous breast biopsies include: Bruising (scarring is usually minimal) Infection Hematoma: pooling of blood trapped inside the biopsy area In general, risks are small and even when one or more of these complications do occur, they usually resolve within a brief period of time with the
Large Core Biopsy (brand name, ABBI)
What is Large Core Biopsy? Large core breast biopsy (also called ABBI, which is a brand name that stands for Advanced Breast Biopsy Instrumentation) is a surgical technique that involves removing an entire intact breast lesion (abnormality) under image guidance.
Sentinel Lymph Node Biopsy

How Does MR Work?
MRI uses magnetic energy and radio waves to create cross-sectional images or "slices" of the human body. The main component of most MR systems is a large tube-shaped or cylindrical magnet. Also, now available are MR systems with a C-shaped magnet or other type of open design.
Biospy Procedure - What is a Biopsy
Biopsy is a medical diagnostic test used to determine the structure and composition of tissue or cells. Biopsy involves sampling cells or living tissue from an organ or other part of the body. In order to make a diagnosis, examination of the tissue sample is then performed using a microscope.
Angiogram - Angiography Procedure Information
Why is Angiograpy Done? X-ray angiography is performed to specifically image and diagnose diseases of the blood vessels of the body, including the brain and heart. Traditionally, angiography was used to diagnose pathology of these vessels such as blockage caused by plaque build up.
Ductogram/Galactogram: Imaging the Breast Ducts
What is Ductography/Galactography and Why is it Performed? Ductography (also called galactography or ductogalactography) is a special type of contrast enhanced mammography used for imaging the breast ducts.
Ductogram/Galactogram: Imaging the Breast Ducts
How is Ductography Performed? The ductography procedure takes between 30 minutes to an hour. Patients referred for ductography most always have nipple discharge at the time of the study.

Who Are The professionals Who Perform CT?
Like all medical imaging examinations, computed tomography (CT) imaging requires a team effort. The computed tomography patient care team is headed by a radiologist. Other team members include CT technologists and frequently nurses who specialize in administering injections.
CT Scan - CAT Scan Imaging - What is a CT Scan
Computed Tomography (CT) imaging, also known as "CAT scanning" (Computed Axial Tomography), was developed in the early to mid 1970s and is now available at over 30,000 locations throughout the world.
Information About Intravenous and Oral Contrast Used in CT
How does oral CT Contrast Work? Barium and gastrografin are made up of substances which weaken (attenuate) x-rays. The oral contrast is swallowed and travels into the stomach and then into gastrointestinal tract.
Information About Intravenous and Oral Contrast Used in CT
During many computed tomography examinations, patients may be asked to take a special contrast agent (orally, rectally or via injection). Intravenous, oral and rectal CT contrast are pharmaceutical agents (liquids) and are sometimes referred to as "dye".

Studies Find Radiation Doses From CT Scans Often Too High For Children
Radiation doses from computed tomography (CT) scans are often higher than needed and may contribute to cancer later in life, according to two new studies published in the American Journal of Roentgenology.
Researchers Investigate Virtual Colonoscopy (CT) For Detecting Colon Cancer
Using non-invasive computed tomography (CT) may detect colon cancer as accurately as conventional colonoscopy, according to a new report.
CT Image Guidance of Minimally Invasive Procedures and Micro-therapy
Since the beginning of computed tomography, radiologists have used CAT/CT to guide simple interventional procedures such as tissue biopsy. Conventional CT guidance of biopsy and other simple procedures is well established.

Introduction to Breast Cancer
Breast pain (mastalgia) is the most common breast related complaint among women; nearly 70% of women experience breast pain at some point in their lives. Breast pain may occur in one or both breasts or in the underarm (axilla) region of the body.
History of Impedance Imaging (T-scan imaging)
Research on impedance imaging dates back to the early 1900s. In 1926, the journal Cancer Research published an article, "The electric capacity of tumors of the breast," [Volume 16: pp. 340-376, by H. Fricke and S. Morse of the Cleveland Clinic Foundation, Department of Biophysics].
T-scan Breast Imaging - Imaginis.com
T-scan (also called electrical impedance scanning or EIS) was approved by the U.S. Food and Drug Administration (FDA) in 1999 to be used as an adjunct tool to mammography in helping to detect breast cancer.
How Does T-scan Imaging of the Breast Work?
The technologist uses the hand-held T-scan probe to image the breast. Image courtesy of Siemens Medical Solutions. The T-scan imaging system is similar in size and appearance to an ultrasound system. There is a small cart-mounted unit with a monitor and keyboard.
What is Electrical Impedance?
Image courtesy of Siemens MedicalElectrical impedance is a measurement of how electricity travels though a given material. Every tissue has different electrical impedance determined by its molecular composition.

Is T-scan Imaging Available In My Area?
The T-scan is a new device and there are approximately 36 installations in 17 countries around the world.
