Spiral CT and Helical CT
In all original CT scanners (1974 to 1987), the x-ray power was transferred to the x-ray tube using high voltage cables wrapped around an elaborate set of rotating drums and pulleys.
Magnetic Resonance Breast Imaging Case Studies
The following cases show high resolution MR breast imaging of five patients. In each case, the breast fat is suppressed using water excitation ("WE") MR imaging.
Magnetic Resonance Breast Imaging Case Studies
Case #1 The following case shows magnetic resonance (MR) breast imaging of a patient with a benign fibroadenoma (a) and invasive lobular carcinoma (b). The two images (left and right) are taken from different planes before contrast injection (gadolinum) and then after contrast injection.
Vacuum-Assisted Biopsy (brand names, Mammotome or MIBB)
How Should Patients Prepare for Vacuum-Assisted Biopsy? To prepare for a vacuum-assisted biopsy, patients may eat a light meal prior to the exam and biopsy procedure. A comfortable two-piece garment should be worn.
Vacuum-Assisted Biopsy (brand names, Mammotome or MIBB)
What is Vacuum-Assisted Biopsy? The relatively new vacuum-assisted breast biopsy is a percutaneous ("through the skin") procedure that relies on stereotactic mammography or ultrasound imaging.
Types of Biopsy
Many types of biopsy exist. The primary physician, radiologist, surgeon or other physician will determine the most appropriate method of biopsy and guidance based on various factors including: the tissue, organ or body part to be sampled how suspicious the abnormality appears the size, shape and oth
Types of Biopsy
Core Needle Biopsy Core needle biopsy (or core biopsy) is performed by inserting a small hollow needle through the skin and into the organ or abnormality to be investigated. The needle is then advanced within the cell layers to remove a sample or core.
Patient Preparation and What To Expect During Percutaneous Needle Biopsy
There are three main types of percutaneous (through the skin) needle biopsy: fine needle aspiration/FNA, core biopsy, suction assisted biopsy. Percutaneous biopsy is minimally invasive, causes little pain and requires no sutures (stitches).
Applications and Clinical Benefits of CT Imaging
Unlike other medical imaging techniques, such as conventional x-ray imaging (radiography), CT enables direct imaging and differentiation of soft tissue structures, such as liver, lung tissue, and fat.
T-scan Impedance Imaging of the Breast is Safe and Effective
Trans-spectral impedance (T-scan) imaging has been developed over the last decade and has been shown to be a safe and effective technique when used as an adjunct to mammography. The T-scan system was granted US Food and Drug Administration (FDA) pre-market approval (PMA) on April 19, 1999.
