“…Therefore, the diagnosis shouldn't be delayed (18). Advantages of MRI compared to CT include multiplanar imaging of cavernous sinus, absence of bone artefacts in the sellar region, abscence of radiation exposure and lesser side effects of gadolinium (16). The findings include isointense signal with muscle on short TR/TE images and isointense signal with fat on long TR/TE images on MRI (13).…”

“…The granulomas might give a heterogeneous appearance. When contrast was administered dynamically, the lesions would enhance slowly and gradually in the subsequent images (16). Haque et al demonstrated the sensitivity of dynamic MR imaging for THS as 83,3%, while the specifity was 100%.…”

“…Plain films might show erosion of the sella turcica (13,15). Orbital phlebography is reported to be abnormal in up to 50% of the cases, but the specifity is low and it is an invasive technique (16,17). Histopathological diagnosis is not prefered due to the proximity to the vital structures.…”

“…Haque et al demonstrated the sensitivity of dynamic MR imaging for THS as 83,3%, while the specifity was 100%. But the major limitation of their study was small sample size (16). MRI might show total or partial regression of the findings after corticosteroid administration on followup exams (6,13,16).…”

“…But the major limitation of their study was small sample size (16). MRI might show total or partial regression of the findings after corticosteroid administration on followup exams (6,13,16). This is an important diagnostic criterion to put the definitive diagnosis of THS and to differentiate it from other cavernous sinus lesions which simulate the disease clinically and radiologically (7).…”

Background: Time-resolved angiography with interleaved stochastic trajectories (TWIST) is a keyhole imaging with frequent sampling of central k-space data and view-sharing for the peripheral k-space of dynamic phases. IT-TWIST is a technique to reconstruct images with a smaller temporal footprint using the same raw data obtained with TWIST by iterative reconstruction. Purpose: To compare image quality between TWIST and IT-TWIST in 3D pituitary DCE-MRI. Study Type: Retrospective observation study. Population: Fifty-one patients (23 men, 28 women) who underwent 3D pituitary DCE-MRI using TWIST between July 2016 and April 2017. Field Strength/Sequence: 3T/TWIST and IT-TWIST. Assessment: Visual evaluation was conducted for image quality of delineation of the pituitary stalk and posterior lobe during the early arterial phase, cerebral white matter near the sella turcica, and the mass lesion. Bolus sharpness of the pituitary stalk, posterior lobe, and bilateral cavernous sinus was evaluated on the enhancement slope map calculated from TWIST and IT-TWIST. Temporal stability of intensity of the nonenhanced area was evaluated on temporal standard deviation (SD) maps calculated from TWIST and IT-TWIST. Statistical Tests: Paired t-test or Wilcoxon rank-sum test was used to test the differences between TWIST and IT-TWIST in both visual evaluation and region of interest evaluation. Results: Scores of visual evaluations for IT-TWIST were significantly better than those for TWIST (P < 0.001) in all items. Enhancement slope for IT-TWIST was significantly higher than that for TWIST in posterior lobe, and right and left cavernous sinus (P < 0.001). Temporal SD for IT-TWIST was significantly lower than that for TWIST in all items, with statistical significance (P < 0.001).
