MR imaging of the Brain without and with contrast

Clinical Information: Mrs. Bevelt is 83 years old and presents with weakness of her right arm and headache (14).
Procedure (MR 202): Sagittal T1-weighted, axial T1, diffusion, T2-weighted, and FLAIR images were obtained through the brain. After intravenous administration of a standard dose of Gadolinium based contrast agent, coronal T1-weighted 3D SPGR and axial T1-weighted spin echo images were obtained. The exact amount of contrast agent given can be retrieved from the IDX system.
Findings: The cortical sulci and ventricle systems are prominent.
There is a wedged shaped area of increase T2 and FLAIR signal on the left side corresponding to a vascular territory of one of the major branches (specify if you can) of the right middle cerebral artery. The area has increased diffusion signal with low signal the ADC (apparent diffusion coefficient) map. The abnormal area involves both the cortex and the white matter. The wedge-shaped area has minimal mass effect. On T1 weighted images the abnormal area shows decreased signal and on post-contrast enhanced images there is no abnormal contrast enhancement.
The pituitary gland, corpus callosum and cerebellar tonsils are normal. There is normal flow void in the major arteries of the circle of Willis. There is no midline shift and no abnormal intra- or extra-axial fluid collections. The brain parenchyma shows no other areas of abnormal signal intensity.
Impression: Left middle cerebral artery acute infarction.

MR imaging of the Lumbar Spine

Clinical Information: Mr. Whitney is 46 years old with right L5 radiculopathy. MRI was requested to evaluate for disk herniation or neural foramina stenosis (14).
Procedure (MR 321): Sagittal T1 and T2-weighted images were obtained through the lumbosacral spine as well as axial proton density and T2-weighted images. No prior studies are available for comparison.
Findings: The vertebral body and disk heights are normal. The alignment of the lumbar sacral spine is normal.
T12/L1: No stenosis of the neural foramina or central canal.
L1/L2: Minimal narrowing of the right neural foramina secondary to facet hypertrophy. The left neural foramina and central canal are normal.
L2/L3: No narrowing of the central canal or neural foramina.
L3/L4: Moderate narrowing of the right neural foramina secondary to facet hypertrophy and a diffuse disk bulge. The central canal is mildly narrowed secondary thickening of the ligamenta flavum and a diffuse disk bulge. The left neural foramen is patent.
L4/L4: Mild narrowing of the right neural foramina secondary to facet hypertrophy and a diffuse disk bulge. The central canal is mildly narrowed narrow secondary thickening of the ligamenta flavum and a diffuse disk bulge. The left neural foramen is patent.
L5/S1: Significant narrowing of the right neural foramen secondary to marked facet hypertrophy and a right paracentral disk herniation. The central canal is within normal limits and the left neural foramen is normal.
Impression:
L5/S1: Significant narrowing of the right neural foramen secondary to marked facet hypertrophy and a right paracentral disk herniation.

MR imaging of the Cervical Spine without contrast

Clinical Information: Mrs. Aura is 55 years old and presents with neck pain and neurologic symptoms indicating a left C6 radiculopathy. MRI was requested to evaluate for an anatomic explanation for her signs and symptoms (14).
Procedure (MR 301): Sagittal T1- and T2-weighted images were obtained through the cervical spine, as well as axial proton density and T2-weighted images.
Findings: The alignment, vertebral body and disk space height are normal. There is decreased signal from the C3/C4, C4/C5 disks indicating dissecation. The signal intensity from the remainder of the disks and vertebral bodies are normal.
C2/C3: No stenosis of the neural foramina or central canal.
C3/C4: Mild narrowing of the right neural foramina secondary to facet hypertrophy and uncovertebral arthropathy. The central canal is normal and the left neural foramen is normal.
C4/C5: No narrowing of the neural foramina or central canal.
C5/C6: Moderate to severe narrowing of the central canal secondary to a posterior spondylotic ridge. There is moderate to severe narrowing of the right neural foramina secondary to uncovertebral arthropathy and facet hypertrophy. The left neural foramen is patent.
C7/T1: No narrowing of the central canal or neural foramina.
Impression:
C5/C6: Moderate to severe narrowing of the central canal and moderate to severe narrowing of the right neural foramina secondary compressing the right C6 nerve.
