ST. PAUL, Minn. - Doctors should use a diffusion MRI scan to diagnose stroke instead of a CT scan, according to a new guideline from the American Academy of Neurology. The guideline is published in the July 13, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology. “While CT scans are currently the standard test used to diagnose stroke, the Academy’s MR images can be viewed in any plane without moving the patient: transverse, sagittal, dorsal and oblique. These different views may help identify a lesion. Contrast Media: CT may be enhanced by the use of contrast agents (e.g.

So zeigt sich zum Beispiel ein Schlaganfall aufgrund einer Durchblutungsstörung in der MRT viel früher als in der CT. Ein Schlaganfall aufgrund einer Hirnblutung kann dagegen mittels CT früh festgestellt werden. Bestimmte Formen der Hirnblutung lassen sich sogar deutlich besser durch CT als durch MRT feststellen.

En CT-röntgen av lungorna (tekniken är sådan att bägge lungorna blir undersökta) ger en stråldos på ungefär 1 till 2 mSv. En vanlig eller konventionell lungröntgen ger en stråldos på ungefär 0,05 mSv. Då kan man tycka att man inte ska undersöka lungorna med CT eftersom den ger så mycket mer strålning. An MRI is suited for examining soft tissue in ligament and tendon injuries, spinal cord injuries, brain tumors, etc. CT scans are widely used in emergency rooms because the scan takes fewer than 5 minutes.
