Endoscopic ultrasound (EUS) or echo-endoscopy is a medical procedure in which endoscopy (insertion of a probe into a hollow organ) is combined with ultrasound to obtain images of the internal organs in the chest, abdomen and colon.
Flow-mediated dilation (FMD) refers to dilation (widening) of an artery when blood flow increases in that artery. [1] [2] The primary cause of FMD is release of nitric oxide by endothelial cells. [1] To determine FMD, brachial artery dilation following a transient period of forearm ischemia is measured using ultrasound. [3]
The comb sign is characterized by the appearance of dilated, prominent vessels in the mesentery of the abdomen, which appears similar to the teeth of a comb. These engorged vessels result from inflammation and increased blood flow in the mesenteric vessels, which is a common response to acute or chronic inflammatory conditions in the gastrointestinal tract.
A normal ECG does not rule out acute myocardial infarction. Mistakes in interpretation are relatively common, and the failure to identify high risk features has a negative effect on the quality of patient care. [12] It should be determined if a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis ...
Blood tests: Blood tests may be ordered to check the levels of substances in the blood that may show a heart problem. Blood tests can also help rule out other conditions. Histopathology of (a) normal myocardium and (b) myocardial hypertrophy. Scale bar indicates 50 μm. Weight of the heart versus the body [27]
Most patients with portal hypertensive gastropathy have either a stable or improving course in the appearance of the gastropathy on endoscopy.However, according to retrospective data, roughly one in seven patients with portal hypertensive gastropathy will develop bleeding (either acute or chronic) attributable to the gastropathy. [1]
Illustration of a Normal Heart vs. Heart with Dilated Cardiomyopathy The progression of heart failure is associated with left ventricular remodeling, which manifests as gradual increases in left ventricular end-diastolic and end-systolic volumes, wall thinning, and a change in chamber geometry to a more spherical, less elongated shape.
The presence of hypoproteinemia, decreased blood lymphocytes, and decreased cholesterol support the diagnosis. Hypocalcemia (low calcium) is also seen due to poor absorption of vitamin D and calcium, and secondary to low protein binding of calcium. Medical ultrasonography may show striations in the intestinal mucosa indicating dilated lacteals ...
