MRI can measure iron amount in the liver using Signal Intensity Ratio (SIR) in which liver intensity (color) is compared to that of the spleen or skeletal muscles. If the liver is darker than these tissues, then it contains an excess of iron. There's a better way, called T2 relaxometry, but it's not widely available.

What's the difference between incarcerated, obstructed, and strangulated hernia? Incarcerated: irreducible, without obstruction of the bowel lumen or reduction in blood supply. Obstructed: irreducible, and the bowel lumen within the inguinal hernia is obstructed (no food or gas can pass), but blood supply is still sufficient. Strangulated: blood supply is reduced leading to ischemia and eventually infarction.

An old age female patient presented with acute-onset colicky abdominal pain, nausea, vomiting, and constipation. Abdominal Examination revealed a likely strangulated inguinal hernia, with dusky color, warm to touch, and absent bowel sounds in the hernia sac. Upright abdominal x-ray revealed multiple air-fluid levels (step-ladder sign), most likely small bowel obstruction. This shows you the importance of physical exam, even in female patients.
