BACKGROUND AND PURPOSE: Recent work has shown that fluid-attenuated inversion
recovery (FLAIR) imaging with contrast enhancement is highly sensitive for detecting …

PURPOSE: To compare contrast material–enhanced T1-weighted and fluid-attenuated
inversion-recovery (FLAIR) magnetic resonance (MR) images in depicting leptomeningeal …

BACKGROUND AND PURPOSE: Postcontrast fluid-attenuated inversion recovery (FLAIR)
imaging effectively depicts parenchymal and leptomeningeal metastases, as reported in …

Seven patients with central nervous system neoplasia and leptomeningeal metastases,
proved either at initial diagnosis or on follow-up with contrast material-enhanced computed …

Forty patients with positive CSF cytology for subarachnoid dissemination of neoplasms were
examined by magnetic resonance (MR) imaging for the detection of intracranial or …

Diagnostic decision making in the case of patients suspected of having leptomeningeal
metastasis (LM) can be very difficult. The results of cerebrospinal fluid (CSF) cytology can be …

We evaluated 14 consecutive patients with leptomeningeal metastasis prospectively, using
both T1-weighted (T1W) gadolinium-DTPA-enhanced MR (Gd-MR) and contrast-enhanced …

AIMS: To assess the range of appearances, and accuracy of various methods of diagnosing
leptomeningeal metastases. MATERIALS AND METHODS: In a retrospective study, the …

Summary Sixty-one patients (34 men; 27 women) ranging in age from 1–74, median 40
years with leptomeningeal metastases (LM) as defined by either positive CSF cytology …

The diagnosis of leptomeningeal metastasis is often difficult and usually requires the
demonstration of malignant cells in the cerebrospinal fluid. Neuroimaging, however, may …
