Detection of Brain Metastases by 3-Dimensional Magnetic Resonance Imaging at 3 T

Effectiveness of 3D T2-Weighted FLAIR FSE Sequences with Fat Suppression for Detection of Brain MR Imaging Signal Changes in Children

“…Accordingly, 3D-FLAIR has found wide application for MR imaging evaluation of the adult brain in healthy subjects and in patients with a variety of diseases or tumors. [14][15][16][17] The lesser conspicuity of CSF flow artifacts in our study is in line with findings in previous reports. [3][4][5][6] So far, few studies have compared the capability of 3D-FLAIR (4 without 6,18-20 and 2 with fat suppression 21,22 ) and 2D-FLAIR in identifying areas of abnormal T2 hyperintensities of the brain.…”

Efficacy of Maximum Intensity Projection of Contrast-Enhanced 3D Turbo-Spin Echo Imaging with Improved Motion-Sensitized Driven-Equilibrium Preparation in the Detection of Brain Metastases

“…They occur in about 20–40% of patients with primary malignancy (123). The number of metastases is a critical prognostic factor as patients with a large number of brain metastases have earlier disease progression and poorer prognosis as compared to those with a smaller number of metastases or no metastases (2456). Moreover, therapeutic strategies are implemented only after considering the number of brain metastases: a single metastasis may be treated with surgery, while small metastases may be treated with stereotactic radiosurgery if they are less than four in number.…”

Evaluation of Thick-Slab Overlapping MIP Images of Contrast-Enhanced 3D T1-Weighted CUBE for Detection of Intracranial Metastases: A Pilot Study for Comparison of Lesion Detection, Interpretation Time, and Sensitivity with Nonoverlapping CUBE MIP, CUBE, and Inversion-Recovery-Prepared Fast-Spoiled Gradient Recalled Brain Volume

“…Multiple investigators have demonstrated improved lesion detection using 3D T1-weighted volumetric fast spin-echo sequences (CUBE, GE Healthcare, Mil-waukee, Wisconsin; sampling perfection with application optimized contrasts by using different flip angle evolution [SPACE], Siemens, Erlangen, Germany; volume isotropic turbo spin-echo [VISTA], Philips Healthcare, Best, the Netherlands). [6][7][8][9][10][11][12][13] CUBE (and similar sequences) uses a variable flip angle technique and higher echo-train length to acquire gap-free volumetric images with reduced acquisition time and specific absorption rate. 7 Furthermore, the black-blood properties offered by CUBE allow good background vascular suppression and provide a higher contrast-tonoise ratio (CNR) than 3D T1-weighted gradient-echo sequences (inversion-recovery-prepared fast spoiled gradient recalled brain volume [IR-FSPGR-BRAVO], GE Healthcare; MPRAGE, Siemens; 3D TFE, Phillips Healthcare).…”
