6. Best investigation for temporal bone fracture is-
A) CT B) MRI C) X-RAY D) Ultrasound
Answers-
Answer-1) (b)
The bone scan is usually normal in multiple myeloma because lytic lesions do not take up isotope.
Answer-2)
Diffuse axonal injury (DAI) is a frequent result of traumatic deceleration injuries and a frequent cause of persistent vegetative state in patients. DAI is the most significant cause of morbidity in patients with traumatic brain injuries, which most commonly are the result of high-speed motor vehicle accidents. Typically, the process is diffuse and bilateral, involving the lobar white matter at the gray-white matter interface. The corpus callosum frequently is involved, as is the dorsolateral rostral brainstem. The most commonly involved area is the frontal and temporal white matter, followed by the posterior body and splenium of the corpus callosum, the caudate nuclei, thalamus, tegmentum, and internal capsule.
Answer-3)
Meningiomas are usually dural-based tumors that are isoattenuating to slightly hyperattenuating. They enhance homogeneously and intensely after the injection of iodinated contrast material. Perilesional edema may be extensive. Hyperostosis and intratumoral calcifications may be present. The tumor compresses the brain without invading it. An enhancing tail involving the dura may be apparent on MRI.
Answer-4)
Meningiomas are the second most common tumor in the intradural extramedullary location, second only to tumors of the nerve sheath. Meningiomas account for approximately 25% of all spinal tumors.MRI demonstrates the intradural extramedullary location of meningiomas. Lesions are usually isointense to spinal cord on both T1-weighted and T2-weighted images. Lesions are sometimes hypointense on T1-weighted images and hyperintense on T2-weighted images.
Answer-5) A Vein of galen malformation
Answer-6) A
for bony temporal bone – CT for inner ear- MRI for facial nerve- MRI

Did you know that-
"We always pictured Gray as an old man with white hair and glasses, you know, that professor type. So I was shocked to find out that he was only 31 when he wrote Gray’s Anatomy. He did so much as a young man, imagine what he could have accomplished had he lived a full life. He is truly inspirational...."

Waits for scan results 'too long'
Detailed report in BBC HEALTH NEWS
"Waits for tests have come downWaits for the results of X-rays and other scans in England are often too long, a report finds. But two out of three doctors and nurses said they often did not get results when needed, and a half said the delays affected patient decisions daily."
Average wait for a non-urgent CT scan:
Seven weeks in 2001
Just over five weeks in 2005
Average wait for an MRI scan:
21 weeks in 2001
14 weeks in 2005
Seems like Teleradiology Providers is on th right track...

Came across this very useful teaching resource from ACR known as Case in point. I suggest this link all radiology residents especially the ones who are about to appear for their examination. It is very easy to subscribe to the "case in point" via your email.
