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-enhanced coronal images, which are critical for the identification of small microadenomas.

This section of the website will explain how to plan for an MRI pituitary fossa(sella turcica), protocols for MRI pituitary fossa, how to position for MRI pituitary fossa and indications for MRI pituitary fossa

2008年8月10日 · In order to analyze a sellar or parasellar mass on MRI we use the following anatomic approach: First identify the pituitary gland and sella turcica. Then determine the epicenter of the lesion and whether it is in the sella or above, below or lateral to the sella. If it is in the sella, determine whether or not the sella is enlarged.

2024年6月28日 · MRI protocol for pituitary gland is a group of MRI sequences put together to improve sensitivity and specificity for the assessment of lesions of the pituitary gland (e.g. pituitary adenoma) and other sellar and suprasellar abnormalities (check the article on pituitary region masses for some examples).

2024年8月20日 · An empty sella, also known as an empty pituitary fossa, refers to the appearance of the sella turcica when the pituitary gland appears shrunken or invisible and CSF fills the space instead.

Magnetic resonance imaging (MRI) of the turcic sella (pituitary gland) This photo gallery presents the anatomy of pituitary gland by means of MRI (T2-weighted coronal views, T1-weighted sagittal and coronal views).

MRI findings include a thinned/flattened pituitary gland along the floor of the sella, with the infundibulum in its normal midline position. The flattened pituitary gland has normal MRI signal characteristics and contrast enhancement.

2023年1月16日 · Before the 1970s, plain radiographs were used to assess for osseous changes in the sella turcica. Expansion of the sella turcica suggests the presence of a mass lesion within the pituitary fossa. However, the presence of abnormalities on skull radiographs is neither sensitive nor specific for pituitary lesions.

2018年11月8日 · The finding of an empty sella turcica is particularly common on MR, in no small part because of the frequent use of T1-weighted sagittal images and the ease of visualization of the pituitary gland, stalk, and sella turcica.

2019年4月4日 · The best magnetic resonance sequence to identify a pituitary lesion is coronal, thin, 3-mm magnified postcontrast images of the sella turcica. The sella is a transverse depression crossing the midline at the superior surface of the sphenoid bone that contains the pituitary gland, or hypophysis.
