Dissecting Aneurysm of the Peripheral Posterior Inferior Cerebellar Artery
¶ Dissecting aneurysms of intracranial posterior circulation have recently been shown to be less uncommon than previously thought. However, those involving the posterior inferior cerebellar artery (PICA) and n...

Transsphenoidal “Cross Court” Approach Using a Slightly Modified Speculum to Reach Pituitary Adenomas with Lateral Growth
¶ Background. The purpose of this study was to evaluate the usefulness of an oblique “cross court” transsphenoidal approach using a speculum with slightly modified projections for pituitary adenomas showing later...

Surface anatomy scanning (SAS) in intracranial tumours: comparison with surgical findings
We evaluated the usefulness of surface anatomy scanning (SAS) in intracranial tumours, comparing it with surgical findings. We examined 31 patients with brain tumours preoperatively. The tumours included 16 me...

Use of fast spin-echo sequence in T2-weighted and dynamic contrast-enhanced MRI of sellar lesions
We evaluated fast spin echo (FSE) sequences in dynamic and T2-weighted MRI of sellar lesions. We examined 25 patients with sellar lesions by dynamic FSE imaging (400/17, ETL 8, 256 × 128, 2 signal averages eve...

MR angiography of arteriovenous malformations: usefulness of phase-contrast with different velocity encoding
To evaluate the usefulness of MR angiography in arteriovenous malformations (AVM) and compare the phase-contrast (PC) with different velocity encoding (VENC) and time-of-flight (TOF) techniques, we prospective...

MRI of intracranial germ cell tumors
We reviewed MRI findings in proven intracranial germ cell tumours in 22 cases, 12 of whom received Gd-DTPA. On T1-weighted images, the signal intensity of the tumour parenchyma was moderately low in 19 cases a...

Utility of MR angiography in intracranial aneurysms: statistical correlation and surgical benefits of the 3-D time-of-flight method
We evaluated the clinical benefit of three-dimensional (3-D) time-of-flight (TOF) MR angiography (MRA) and spoiled GRASS (SPGR) source imaging for intracranial aneurysms. MRA was performed on 40 aneurysms conf...

Displacement of the normal pituitary gland by sellar and juxtasellar tumours: surgical-MRI correlation and use in differential diagnosis
We compared the position of the normal pituitary gland as estimated by gadolinium (Gd)-DTPA-enhanced MRI, with its position at surgery in 40 patients with intra- and juxtasellar tumours: 22 pituitary adenomas,...

MRI of pituitary adenomas: the position of the normal pituitary gland
The position of the normal pituitary gland, assessed using gadolinium-enhanced MRI was compared with the position found at surgery for pituitary adenoma in 25 patients. The tumours were five microadenomas and ...
