- Gas in the Cavernous Sinus Key Points
“In patients without symptoms referable to the cavernous sinus, gas in the cavernous sinus does not appear to be a significant finding. The gas is most likely the result of venous air emboli from intravenous lines or penetrating trauma.”

- Discrimination of Metastatic from Acute Osteoporotic Compression Spinal Fractures with MR Imaging Key Points
“However, in our study the signal intensity on fast spin-echo T2-weighted images played little role in distinguishing between acute benign osteoporotic and metastatic compression fractures.”
“Therefore, signal intensity on fat-suppressed contrast-enhanced T1-weighted images was not useful in differentiation of acute osteoporotic from malignant compression fractures, which is consistent with results of previous studies”
“A convex posterior border of the vertebral body, abnormal signal intensity of the pedicle or posterior element, an epidural mass, a focal paraspinal mass, and other spinal metastases are suggestive of metastatic compression fractures.”
“A low-signal-intensity band on T1- and T2-weighted images, spared normal bone marrow signal intensity of the vertebral body, retropulsion of a posterior bone fragment, and multiple compression fractures are suggestive of acute osteoporotic compression fractures.”
