The liver is a pyramid-shaped organ that lies within the upper right side of the abdomen. In a typical liver biopsy, a needle is inserted through the rib cage or abdominal wall. The needle goes into the liver to take a sample for examination. The procedure can also be performed by inserting a needle into the jugular vein. A catheter is then passed through the veins, down to the liver, to take the sample.

A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. The sample is examined under a microscope by a doctor who specializes in the effects of disease on body tissues (a pathologist) to detect abnormalities of the liver.

A mammogram is an X-ray of the breast. It can find changes in the breast when a lump is too small for you or your doctor to feel.

Remind your technologist that you have breast implants. Also mention if you are or think you might be pregnant, have had a breast biopsy or surgery, are breastfeeding or have moles on or near your breasts.

For women at high genetic risk, adding MRI screening to mammography may improve early detection of breast cancer.

This report provides information on using the latest detection methods, understanding your diagnosis, and choosing the most effective treatment.

Digital mammography is poised to replace the standard version, but studies show them to be about equal in effectiveness at detecting cancers, depending on age and breast density. Ultrasound and MRI are also useful tools for detection in some women.

An MRI of the head is a noninvasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.

Like all other parts of the body, the brain and central nervous system are made up of cells that ordinarily grow and divide to create new cells as needed. This is usually an orderly process; but when cells lose their ability to grow normally or to die off naturally, they divide too often and produce tumors that are made up of these extra cells.

Part of the central nervous system located in the skull. Controls mental and physical actions of the organism.

Congenital brain defects are a group of disorders of brain development that are present at birth. Brain development begins shortly after conception and continues throughout the growth of a fetus.

Brain abscess is a bacterial infection within the brain. The brain is usually well insulated from infection by bacteria, protected by the skull, the meninges (tissue layers surrounding the brain), the immune system, and the highly regulated barrier between the bloodstream and the brain.

A brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain, such as Alzheimer ' s disease , tumors, infection, or inflammation. Purpose By examining the tissue sample under a microscope, the biopsy sample provides doctors with the information necessary to guide diagnosis and treatment.

A brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain.

Congenital brain defects are a group of disorders of brain development. Brain development begins shortly after conception and continues throughout the growth of a fetus.

The brain is the part of the central nervous system located in the skull. It controls the mental processes and physical actions of a human being.

The brain is a large mass of soft nervous tissue made up of both neurons and supporting glial cells lying within the cranium of the skull. The brain contains both gray and white matter.

Magnetic resonance imaging (MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images.
