Why would a doctor order a CT scan after a colonoscopy?
The major reason for performing CT colonography is to screen for polyps or cancers in the large intestine. Polyps are growths that arise from the inner lining of the intestine. A very small number of polyps may grow and turn into cancers.
What does fat stranding on a CT scan mean?
Fat stranding refers to an abnormal increased attenuation in fat, (in the mesentery, omentum, retroperitoneum, or subcutaneous fat). The underlying pathophysiologic process is increased edema and engorgement of lymphatics.
What is a precancerous lesion in the colon?
Precancerous conditions of the colon or rectum are changes to cells that make them more likely to develop into cancer. These conditions are not yet cancer. But if they aren’t treated, there is a chance that these abnormal changes may become colorectal cancer.
Can I have an MRI instead of a colonoscopy?
NEW YORK (Reuters Health) – The use of magnetic resonance imaging, or MRI, may offer a more tolerable alternative to conventional colonoscopy in screening for colon cancer, new research suggests. With MRI colonography, images are taken of the colon that resemble those seen with colonoscopy.
What is fatty infiltration in skeletal muscle?
Fatty Infiltration in Skeletal Muscle: Cellular and Molecular Mechanisms. There are several stem cell populations in skeletal muscle, the most well defined being muscle satellite cells (SCs), which lie below the basil lamina of muscle fibers and contribute to myogenesis during the process of muscle regeneration.
What does pericolonic fat infiltration indicate?
Pericolonic fat infiltration may indicate tumor extension beyond the serosal layer (T2 vs T3) [9], [10]. However, this finding is nonspecific and may represent inflammatory reaction, fibrosis, or congestion [11].
What is the pathophysiology of fatty accumulation in muscle?
The cellular origins of fatty accumulation in muscle arise through several different pathways (Figure (Figure1).1). One direct route is viathe accumulation of lipid within myofibers themselves, known as intramuscular fat or intramyocellular (IMC) lipid (28–30).
How to prevent fatty infiltration of muscles with aging?
One of the most effective countermeasures against fatty infiltration of muscle with aging is physical activity and regular exercise.
