OBJECTIVE: To check the diagnostic accuracy of Three-T magnetic resonance imaging (MRI) with thin-slice 3D T1 VIBE sequence to 128-slice laptop tomography (CT) in pars stress fractures of the lumbar backbone.
MATERIALS AND METHODS: Three-T MRI and CT of 24 sufferers involving 70 pars interarticularis had been retrospectively reviewed by 4 blinded radiologists. The fracture morphology (full, incomplete, or regular) was assessed on MRI and CT at completely different time factors. Pars interarticularis bone marrow edema (current or absent) was additionally evaluated on MRI.
RESULTS: In complete, 14 full fractures, 31 incomplete fractures and 25 regular pars had been detected by CT. Bone marrow edema was seen in seven of the entire and 25 of the unfinished fractures. The general sensitivity, specificity and accuracy of MRI in detecting fractures (full and incomplete) had been 97.7, 92.Three, and 95.7 %, respectively. MRI was 100 % correct in detecting full fractures. For incomplete fractures, the sensitivity, specificity, and accuracy of MRI had been 96.7, 92.zero, and 94.6 %, respectively.
CONCLUSIONS: Three-T MRI with thin-slice 3D T1 VIBE is 100 % correct in diagnosing full pars fractures and has glorious diagnostic means within the detection and characterization of incomplete pars stress fractures in comparison with CT. MRI has the added benefits of detecting bone marrow edema and doesn’t make use of ionizing radiation.
