Vertebral compression is also a rather late radiographic sign, but further differential diagnoses of malignancy and osteoporosis must be considered on presentation of this finding. The diagnosis of CNO must, therefore, rely on the clinical picture, in addition to imaging studies. T2-weighted MRI ...
While multiple sclerosis is not hereditary, genetics are believed to play a role. In the U.S., the chances of developing MS are one in 750. Having a first-degree relative (parent, sibling) increases the risk to up to 5%. An identical twin of someone with MS has a 25% chance of bei...
One of the main ways to diagnose multiple sclerosis is an MRI (magnetic resonance imaging) scan. Characteristic areas of demyelination will show up as lesions on an MRI scan. On the left is a brain MRI scan of a 35-year-old man with relapsing remitting multiple sclerosis that reveals multip...
This review focuses mainly on the imaging diagnosis, treatment, and complications of acute cholecystitis which is the most common benign disease of the gal
acquired with echo times between 25–100 ms. Blood suppression is obtained through double-inversion recovery preparation.bT2w image along with quantitative T2 map of an advanced plaque (SMsmooth muscle,*lumen). Semi-automated segmentation of plaque components from the T2 map is shown on the right...
As a result, MRI is performed solely on a proportion of the population screened by obstetric ultrasound, which leads to a difference in the subjects of these two groups and a higher diagnostic possibility in the MRI group. In such case, the diagnostic accuracy of MRI may be overestimated. ...
In the case we reported, the abnormal brain MRI may be a common physiological manifestation in infants. Besides, the patient’s seizure is controlled well by topiramate monotherapy. While the patients with FCD usually presented frequent and refractory seizures. Therefore, it is unlikely that the ...
Note the mass effect on the lateral ventricle despite the lack of a mass or hemorrhage. Image from Dr Evans. Figure 2. Axial T2-weighted MRI through the body of the lateral ventricles, showing superior extension of a right middle cranial fossa lesion. The lesion is homogeneous, with no ...
These HCC appear hypointense during the hepatobiliary phase (MRIHB). In some HCC, OATP expression is increased (O+). In these HCC, the signal intensity will depend on MRP2 expression. When MRP2 expression is high, the HCCs usually appear hypointense. Hyperintense (or isointense) HCCs during ...
