Cancer Blood Tests Under 50
If you are in your thirties or forties and have looked into multi-cancer early detection blood tests, you have probably run into the same wall: the age requirement. These tests are offered to adults 50 and older, and if you are younger, the answer is generally no. That surprises people, particularly people who have read […]
Signal vs. Anatomy
“Can a blood test detect cancer in the body?” is one of the most common questions people bring to us, and the honest answer depends entirely on which blood test you mean. There are really only two ways to look for cancer. You can look for a signal — some trace in the blood that […]
Tornwaldt Cyst
A Tornwaldt cyst is a harmless midline nasopharyngeal cyst, almost always found incidentally on MRI and rarely requiring any treatment.
Toxoplasmosis
Toxoplasmosis is a common parasitic infection that is usually silent. Brain MRI is useful for cerebral toxoplasmosis in immunocompromised patients.
Liver Fat Fraction (MRI-PDFF)
Liver fat fraction, measured by MRI-PDFF, quantifies fat in the liver as a percentage. Above roughly 5% meets the definition of hepatic steatosis.
Epidermoid Cyst
An epidermoid cyst is a slow-growing, benign lesion that MRI can distinguish from an arachnoid cyst using diffusion-weighted imaging.
Sarcoidosis
Sarcoidosis is an inflammatory condition in which tiny clusters of inflammatory cells, called granulomas, form in one or more organs of the body. It most often affects the lungs and the lymph nodes in the chest, but because it can appear almost anywhere, it is described as a multi-system condition — the skin, eyes, heart, […]
Gallstones
Gallstones are hardened deposits that form inside the gallbladder, the small pear-shaped organ beneath the liver that stores bile to help digest fat. They can be as small as a grain of sand or as large as a golf ball, and a person may have one stone or many. Gallstones are very common — they […]
Diverticulosis
Diverticulosis is a condition in which small pouches, called diverticula, form in the wall of the colon (the large intestine). These pouches develop where the colon wall is naturally a little weaker, and over time small sections can bulge outward. Diverticulosis is very common, especially with age. Estimates suggest it is present in a large […]
Enlarged Heart
Cardiomegaly is the medical term for an enlarged heart. It is helpful to understand that cardiomegaly is usually a sign of another condition rather than a disease on its own. When the heart works harder than normal for a long time, or when the heart muscle itself is affected, the heart can enlarge in much […]
