The complex type is unrecognizable as dental tissues, usually presenting as a radioopaque area with varying densities.

None of these are radioopaque, so they are difficult to view with radiologic imaging unless they are soaked in contrast prior to injection.

Electronic portal imaging device detection of radioopaque markers for the evaluation of prostate motion during megavoltage irradiation: a clinical study.

Information concerning motility of the entire colon has been obtained by indirect measures such as the movement of radioopaque markers or barium to assess colonic transit time.

The test involves injection into a vein (usually in the arm) of a radioopaque substance, and time is allowed for the bloodstream to carry it to the cerebral veins - at which point the scan is performed.

Mean gastric clearance of radioopaque markers ingested with the test meal was significantly (p<0.02) faster in patients without cardiovascular autonomic neuropathy as compared to patients with cardiovascular autonomic neuropathy (Fig 2).

If a kidney stone is suspected (e.g. on the basis of characteristic colicky pain or the presence of a disproportionate amount of blood in the urine), a kidneys, ureters, and bladder x-ray (KUB film) may assist in identifying radioopaque stones.
