TL;DR
Interpretation of MR imaging for pituitary microadenomas in CD can be inherently difficult, and the resulting interrater variability may contribute to differing impressions of lesion location.
In a diagnostically heterogeneous real-world cohort, 1H-MRS significantly improved the accuracy achievable with conventional MRI alone and substantially increased reported diagnostic confidence, with high specificity but only moderate sensitivity.
Glioblastoma (GBM) is the most common malignant primary brain tumor in adults with nearly universal progression despite aggressive treatment. Distinguishing true tumor recurrence from treatment-related effects (pseudoprogression) remains challenging with conventional contrast-enhanced MRI, as both can produce similar i...
Objective Preoperative localization is essential for the surgical management of primary hyperparathyroidism (PHPT). Ultrasound and 99mTc-sestamibi SPECT/CT are first-line imaging modalities, while MRI’s role is less defined. This study aimed to evaluate MRI for parathyroid adenoma localization in PHPT and compare it wi...
The incomplete ring enhancement sign is a potential diagnostic sign of brain radionecrosis and associated morphologic features, including fragmentation, satellite foci, and watershed localization, may reinforce the diagnosis.
DPAs involving a corticotroph component should be considered as a possible explanation for persistent hypercortisolism after TSS when the resected lesion is negative for ACTH and T-PIT and the role of adjunctive molecular imaging remains preliminary.
