Marc J. Gollub, MD, FACR

I am a diagnostic radiologist with special expertise in gastrointestinal malignancies, and I use cutting-edge methods (MRI, virtual colonoscopy, PET and CT scanning, CT enteroclysis, CT enterography, and barium studies) to diagnose and stage cancers of the esophagus, stomach, small intestine, and colon. I also serve as director of the Radiology Department's CT section and director of gastrointestinal radiology.

As a member of the colorectal cancer Disease Management Team (DMT) I collaborate closely with Memorial Sloan-Kettering’s colorectal surgeons and gastroenterologists to accurately diagnose and stage colon cancer, malignant bowel obstruction, recurrent rectal cancer, and other gastrointestinal problems. I very much enjoy working with patients, and learn as much as I can from them about their symptoms to aid my interpretation of their images. I also enjoy explaining the imaging findings to patients to give them a better understanding of their illness.

My research interests include early detection of colon cancer through combined structural and molecular imaging approaches. For this work I have been awarded three grants (from The Society of Memorial Sloan-Kettering Cancer Center and The Society of Gastrointestinal Radiologists). I am particularly involved in research using MRI to improve rectal cancer staging. As director of CT, I am interested in how best to use Dual Energy CT, and in keeping radiation doses as low as possible while obtaining maximum information.

I lecture and present research at national and international meetings of professional groups such as the Society of Gastrointestinal Radiologists and the Radiological Society of North America. I am also a member of Memorial Sloan-Kettering’s Research Council and have input on the radiologic aspects of every research study performed at the Center. As a reviewer for several leading journals I have rapid access to the most recent advances in radiology and oncology.

bowel (BOW-ul)

The long, tube-shaped organ in the abdomen that completes the process of digestion. The bowel has two parts, the small bowel and the large bowel. Also called intestine.

(http://www.cancer.gov/dictionary)

cancer (KAN-ser)

A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.

colon (KOH-lun)

The longest part of the large intestine, which is a tube-like organ connected to the small intestine at one end and the anus at the other. The colon removes water and some nutrients and electrolytes from partially digested food. The remaining material, solid waste called stool, moves through the colon to the rectum and leaves the body through the anus.

colon cancer (KOH-lun KAN-ser)

Cancer that forms in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids).

colonoscopy (KOH-luh-NOS-koh-pee)

Examination of the inside of the colon using a colonoscope, inserted into the rectum. A colonoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease.

colorectal (KOH-loh-REK-tul)

Having to do with the colon or the rectum.

esophagus (ee-SAH-fuh-gus)

The muscular tube through which food passes from the throat to the stomach.

gastrointestinal (GAS-troh-in-TES-tih-nul)

Refers to the stomach and intestines. Also called GI.

imaging (IH-muh-jing)

In medicine, a process that makes pictures of areas inside the body. Imaging uses methods such as x-rays (high-energy radiation), ultrasound (high-energy sound waves), and radio waves.

malignant (muh-LIG-nunt)

Cancerous. Malignant cells can invade and destroy nearby tissue and spread to other parts of the body.

medicine (MEH-dih-sin)

Refers to the practices and procedures used for the prevention, treatment, or relief of symptoms of a diseases or abnormal conditions. This term may also refer to a legal drug used for the same purpose.

MRI

A procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. MRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray. MRI is especially useful for imaging the brain, the spine, the soft tissue of joints, and the inside of bones. Also called magnetic resonance imaging, NMRI, and nuclear magnetic resonance imaging.
