2024年7月17日 · MRI is the mainstay of imaging for pituitary microadenomas and requires dedicated pituitary sequences (thin slice, small field of view, dynamic contrast acquisition). …

We have developed a new MRI exami-nation for pituitary microadenomas on our 3T MAGNETOM Skyra scanner which combines high-resolution volumetric as well as a multiphase, dynamic …

2023年7月18日 · A typical targeted MRI examination of the pituitary region includes coronal and sagittal small field of view T1 and T1 post-contrast images, as well as dynamic contrast …

2023年10月15日 · Magnetic resonance imaging (MRI) is the mainstay imaging modality of choice for evaluating pituitary adenomas (PAs). 1-4 PAs are diagnosed when patients present with …

2021年10月1日 · The increased signal intensity of 3-T MRI is beneficial in detection of very small microadenomas, for example in the setting of Cushing syndrome, particularly when combined …

Venous sinus sampling is very accurate in diagnosing pituitary or ectopic lesions, but dynamic MRI is more accurate than venous sinus sampling in diagnosing the location (left or right …

This article reviews the magnetic resonance imaging techniques that can be used to assess the pituitary gland and describes the imaging characteristics of normal sellar anatomy and …

2012年10月21日 · Pituitary adenomas are the most common lesion in the sella, accounting for 10–15% of all intracranial tumors. Lesions less than 10mm are called microadenomas. …

On brain MRI, pituitary adenoma is characterized by a large mass with heterogeneous signal. Other findings may include remodeling of the floor of the sella and deviation of the pituitary …

Thirty-seven patients with suspected pituitary tumors were evaluated prospectively with MR imaging at 1.5 T. MR detected a microadenoma at its correct location in all eight patients who …
