  2. John Thomas sign - Wikipedia

    en.wikipedia.org/wiki/John_Thomas_sign

    It refers to the position of a penis as it relates to pathology on an X-ray of a pelvis. 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 ...

  3. Pyelogram - Wikipedia

    en.wikipedia.org/wiki/Pyelogram

    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.

  4. Risser sign - Wikipedia

    en.wikipedia.org/wiki/Risser_sign

    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.

  5. X-ray of hip dysplasia - Wikipedia

    These images confirm soft tissue mass (arrows) in the renal pelvis with contrast excretion into the collecting system (arrowheads). [ citation needed ] CT urography (CTU) is commonly used in the evaluation of hematuria, and specifically tailored to image the renal collecting system, ureters and bladder in addition to the renal parenchyma.

  8. Projectional radiography - Wikipedia

    en.wikipedia.org/wiki/Projectional_radiography

    Projectional radiography relies on the characteristics of X-ray radiation (quantity and quality of the beam) and knowledge of how it interacts with human tissue to create diagnostic images. X-rays are a form of ionizing radiation , meaning it has sufficient energy to potentially remove electrons from an atom, thus giving it a charge and making ...

  9. Linea terminalis - Wikipedia

    en.wikipedia.org/wiki/Linea_terminalis

    The pelvic inlet is typically used to divide the abdominopelvic cavity into an abdominal (above the inlet) and a pelvic cavity (below the inlet). Sometimes, the pelvis cavity is considered to extend above the pelvic inlet, and in this case the pelvic inlet is used to divide the pelvic cavity into a false (above the inlet) and a true pelvis ...
