ROCO_13371

MRI of the head. The apparent pituitary macroadenoma

ROCO_13407

Abscess, lying along the right psoas muscle due to pyogenic spondylodiscitis caused by Streptococcus intermedius in T1 weighted sagittal magnetic resonance imaging scan

ROCO_13419

Sagittal cine phase-contrast magnetic resonance imaging after 5 years. Continuous (patent) cerebrospinal fluid flow is observed from the foramen of Monro to the prepontine cistern. Superior to inferior flow is shown in black (black arrow)

ROCO_13420

Postoperative brain MRI shows the bilateral VAs transposed from the brainstem.

ROCO_13443

Superimposed volumes of interest on T2-weighted image without motion probing gradient. A Posterior limb of the internal capsule, B corpus callosum, C thalamus, D anterior horn of the lateral ventricle

ROCO_13456

14-year-old male with traumatic lipohemarthrosis of the wrist joint. MRI appearance of lipohemarthrosis. Axial, fat-saturated, T2-weighted image at the level of the proximal carpal row demonstrates lipohemarthrosis. Note the three different signal intensities of fat, serum, and the dependent red cells. Anterior or top layer (white asterisk) is of low signal intensity and represents fat. The first fluid-fluid level (arrow) shows the fat floating above the near-water density of serum (curved arrow). The second fluid-fluid level (arrowhead) separates the serum layer (curved arrow) and the dependent red cell layer with high hemoglobin and iron content (black asterisk).

ROCO_13460

Pre-secretin magnetic resonance cholangiopancreatography Whipple. The image shows pancreato-jejunostomy (arrow) and choledocho-jejunostomy (dashed arrow).

ROCO_13473

Radiation necrosis masquerading as late tumor recurrence. Five years after treatment for malignant ependymoma, axial post-gadolinium T1-weighted MRI image showed stable post-treatment changes and no residual or recurrent tumor. [Powerpoint Slide]
