Abstract:We studied 76 patients with endocrinological features of prolactin-secreting microadenoma by MRI, using three dimensional (3D) gradient echo acquisition (FLASH) sequences. MRI revealed a focal signal abnormality in the pituitary in all 37 patients who had not previously taken bromocriptine. However, focal abnormality was shown in only half the patients had been on dopamine agonist therapy; the MRI findings in these 39 patients were not affected by the duration and dosage bromocriptine, nor by the time elapsed … Show more
“…3D‐SGE sequence provides better soft tissue contrast and allows thinner section (down to 1 mm) of pituitary, which improves the spatial resolution of images . Volume interpolated 3D‐SGE (VI‐SGE) sequence is a relatively new 3D‐SGE sequence.…”
VI-SGE MR sequence was better for localization of pituitary microadenomas particularly when DC-SE MR sequence is negative or equivocal and should be used in addition to DC-SE MR sequence for the evaluation of ACTH-dependent CS.

“…In another paper assessing diagnostic value in 76 prolactinoma patients, sensitivity was 75%, but only 15 had a surgically confirmed tumour in the depicted region. These patients were those in which hormonal treatment failed [20]. It obviously led to some scepticism on the diagnostic value of SPGR.…”
We found a high success rate in surgical procedure in terms of the correlation between MR findings and histology, which leads to remission of Cushing's disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
