Purpose To assess the value of secondary signs in helping to diagnose ligamentum teres (LT) injuries. Materials and methods Seventy-nine patients enrolled in a prospective case-control study performed MRI examination of the hip joints. Two groups identified according to their clinical presentation. Group I [54 patients] with clinically suspicious LT injury, Group II [25 patients] with no clinical suspicion of such diagnosis considered as control group examining both hip joints [total 50 examined joints]. Patients of the 1st group performed sonar-guided MR arthrography. Secondary MR signs are correlated with the occurrence of LT injuries. Consensus Diagnosis employs a 5 point confidence score. Results Thirty-one cases show LT injuries in which Bone marrow edema, joint effusion, and coincidental intra-articular pathology was found in 77%, 29% and 19% of cases respectively with (p-value ≤0.001). The combined secondary signs are present in 83% of cases with LT injuries (p ≤ 0.001). The significant alteration in dimensions is in width with mean cut off 4.9 mm of injured LT with 87% specificity. Almost perfect agreement (K = 0.91, p ≤ 0.001) recorded in the consensus interpretation between the two radiologists. Conclusion The presence of the secondary signs of LT injury raises the suspicion for such diagnosis.

Introduction Acetabular cup version is crucial for successful total hip arthroplasty (THA). Many methods have been described for measurement of cup version angle. The aim of this study is to assess the accuracy of five commonly used methods for measurement of acetabular cup version in plain antero-posterior views of the pelvis and hip. Material and methods Sixty primary THA cases were subjected postoperatively to plain A-P of the pelvis (AP-P), A-P view of the hip (AP-H), and computed tomography (CT) imaging. The acetabular cup version was measured in AP-P and AP-H by five methods (Lewinnek, Widmer, Hassan et al., Ackland et al., and Liaw et al.). These measurements were compared to the CT measurement. Results All plain X-ray methods showed no significant differences from the CT, except …

Aim: Assessing the diagnostic role of multiparametric MRI (mpMRI) in indeterminate mammographic breast lesions and postulated a diagnostic model for MRI interpretation integrating the morphological, and functional parameters. Material and Methods: Two hundred forty patients included in a self-control retrospective study in a tertiary center. All patients examined with 1.5T MR unit using multiparametric studies including morphological analysis followed by functional evaluation via MR diffusion (MR-DWI), spectroscopy(MRS), and kinetic enhanced curves (DCE-MRI). Diagnostic performance of each parameter was evaluated alone and in combination. The histopathological results were the standard of reference. Results: Combined mpMRI parameters possess a moderate agreement (κ=0.435) with 23.5% false discovery rate (FDR) and an overall accuracy of 78%.On the other hand, combined mpMRI data after omitting MRS data show almost perfect agreement (κ=0.923)with histopathological data and recorded 100% specificity, 90% specificity, 5% FDR and zero% for both false omission rate (FOR) and false-negative rate (FNR). The Quantitative analysis of DWI with ADC map shows a significant statistical value for mean ADC (m-ADC) value and relative ADC (r-ADC) value. The former has cutoff value 1.1x10-3 mm2/sec with higher specificity 97.5% while r-ADC has cutoff value 0.42x10-3 mm2/sec with quite lower specificity 85%. Perfect agreement in the interpretation of DCE-MRI curves, MR-DWI, and MRS with κ =0.92,0.9 and 0.84 respectively. Conclusion: Tailored combined multiparametric MRI is a potent diagnostic tool in the …
