When the penis (visible on the X-ray as a shadow) points towards the same side as a unilateral medical condition such as a broken bone, this is considered a "positive John Thomas sign," and if the shadow points to the other side, it is a "negative John ...
X-ray of the hips of a 40-year-old female, with dysplasia of her right hip.

The Risser sign is an indirect measure of skeletal maturity, whereby the degree of ossification of the iliac apophysis by x-ray evaluation is used to judge overall skeletal development. Mineralization of the iliac apophyses begins at the anterolateral crest and progresses medially towards the spine.
The x-ray film represents a two-dimensional image of a three-dimensional object due to the summary projection of different anatomical structures onto a planar surface. It requires certain skills for the correct interpretation of such images. Radiological anatomy is a necessary component of training for medical students and radiologists.

The standard set of X-rays for a skeletal survey includes X-rays of the skull, entire spine, pelvis, ribs, both humeri and femora (proximal long bones). It is more effective than isotope scans at detecting bone involvement in multiple myeloma. Although significantly less sensitive than MRI, it is easier to include more bones. A study found that ...
The American Airlines statement read in part: "American has made the difficult decision to suspend daily service between Miami (MIA) and Port-au-Prince, Haiti (PAP)," the spokesperson said.
Immediately after the contrast is administered, it appears on an X-ray as a 'renal blush'. This is the contrast being filtered through the cortex. At an interval of 3 minutes, the renal blush is still evident (to a lesser extent) but the calyces and renal pelvis are now visible.
