ABSTRACT
Background: Familiarity with the normal calcaneal anatomy is important for understanding fracture mechanisms and classification schemes. Clinical presentation at the time of evaluation generally includes [a] a history of a fall from a height, and [b] certain signs that aid the physician in identifying possible calcaneal fractures
Purpose: To look at the role played by the multi detector computed tomography [MDCT] in assessing calcaneus fractures and delineate the fracture fragment which help in decision making in the management of extra and intra articular fractures of the calcaneum and pre-operative planning
Patients and Methods: This study will be conducted on patients with calcaneal fractures suspected clinically or by x ray diagnosis. The patient will be referred from orthopaedic department at Ain Shams University Hospitals; the patient will be investigated using MDCT
Results: This study included 44 feet of 41 patients [three bilateral]; 35 males and 6 females, representing 85.4% and 14.6% of all patients respectively, their mean age was 34.22 years, we observed that calcaneal fractures commonly occur in male than female
Conclusion: Multi detector CT is the best method of assessing calcaneus fracture in order to decide management. It delineates the fracture fragments and help in making the pre-operative planning of the fracture
ABSTRACT
Hepatocellular carcinoma [HCC] is the most common primary liver malignancy. Surgical resection and local ablative therapies represent the most frequent first lines therapies adopted when liver transplantation cannot be offered
Aim of the work: was to evaluate the feasibility of DWI and the corresponding ADC values to detect tumor response after radiofrequency ablation for hepatocellular carcinoma
Materials and methods: MR examinations were done for 20 HCC patients post-RFA. Pre and postgadolinium enhanced images as well as DW sequences were performed. ADC values of ablation zones and liver parenchyma were assessed. ADC values of ablation zones and adjacent signal alterations identified in DWI were analyzed
Results: residual or recurrent lesions were detected in 4 patients [20%]. The mean ADC value of ablated zones differed significantly from that of normal liver parenchyma. The corresponding ADC values were significantly lower in patients with residual lesion than in patients without residual lesion
Conclusion: it could be concluded that DWI is a feasible follow-up tool for postablation liver contributing in detection of residual lesion
ABSTRACT
Background: patello-femoral stability is principally influenced by anatomic factors. Understanding the anatomy and biomechanics of the patello-femoral joint provides insight into the etiology and management of patellar instability. Magnetic resonance imaging [MRI] has emerged as an auxiliary method for investigating patello-femoral instability, particularly for detecting osteochondral lesions and for evaluating the medial patello-femoral ligament [MPFL]
Objective: descriptive study including analysis of MRI knee done for patients with patellar instability suspected clinically with or without history of trauma
Patients and Methods: thirty patients were included in the study, all with suspicious patellar instability from Ain-Shams University orthopedic clinic and other private clinics. A cross-sectional study was held where all the patients under-went MRI routineknee protocol. MRI knee images were interpreted for identification of different pathologies contributing to patellar instability
Results: sixty percent of the patients included in our study had MPFL injury, 43% showed patella alta, 83% showed trochlear dysplasia [by different measurements] and 43% showed lateral displacement of TT
Conclusion: MRI the modality of choice in diagnosing different pathologies of patellar instability, for its value in assessing soft tissue structures, detailed imaging of the cartilage and applying all measurement required
