MR of the spine with a fast T1-weighted fluid-attenuated inversion recovery sequence.
To optimize a T1-weighted fast fluid-attenuated inversion recovery (FLAIR) sequence using computer-simulated data and to study its clinical utility for imaging the spine. ⋯ The optimized T1-weighted fast FLAIR technique has definite advantages over spin-echo sequences for imaging the spine. Comparable acquisition times render the FLAIR sequence the method of choice for T1-weighted imaging of the spine.

Evaluation of intracranial lesions with inversion recovery half-Fourier single-shot turbo spin-echo MR: initial observations.
To determine the value of inversion recovery half-Fourier single-shot turbo spin-echo (IR-HASTE) MR sequences in the characterization of a variety of intracranial lesions, with the focus on differentiating between epidermoids and nonneoplastic cystic lesions. ⋯ IR-HASTE sequences provide a rapid and reliable imaging method for differentiating among epidermoids, arachnoid cysts, and solid neoplasms. This technique also provides information about the continuity of the multicystic lesions in terms of the differences in their TI nulling values. For solid intraaxial masses, the use of IR-HASTE helps to differentiate intratumoral cysts and necrosis from solid components.

Case ReportsEndovascular thrombolysis in deep cerebral venous thrombosis.
We present two cases of acute thrombosis of the internal cerebral veins, vein of Galen, and straight sinus without sagittal sinus involvement. Both patients had hydrocephalus and severe edema of the basal ganglia and thalami, one with hemorrhagic infarction of the thalamus. ⋯ Thrombolysis was continued until a patent channel with brisk flow in the venous structures was achieved. Both patients survived with minimal neurologic deficits.
