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
Background: early detection and diagnosis of hepatic focal lesions are an important step in clinical work, which would allow effective surgical or mini-invasive therapy. With the advances in magnetic resonance imaging [MR] technology, diffusion-weighted magnetic resonance imaging [DWI] is now widely used as a standard imaging sequence in clinical work and shows its potential benefit in evaluation of the focal hepatic lesions
Aim of the work: the use of MR Diffusion imaging with both low and high B values to detect and differentiate between benign and malignant hepatic focal lesion
Methodology: the present study included 30 patients. They were El-Demerdash hospital patients with hepatic focal lesions. Patients underwent US or CT before MR examination
Results: thirty patients were included in this study, 20 males and 10 females. The patient's age was ranging from 33 to 60 years. There were 24 primary hepatic focal lesions, [36.7% HCC, 3.3% focal nodular hyperplasia, 3.3% cysts, 13.3% hemangiomas, 6.7% cholangiocarcinoma, 16.7% regeneration nodule] and 6 metastatic lesions
Conclusion: we hope to use DWI to be helpful in the characterization of focal liver lesions, especially if the lesions show non classic appearance of contrast enhancement in Triphasic CT study and in patients with renal insufficiency with inability to use contrast enhancement
Recommendations: in our opinion, DWI is a useful adjunct to routine liver imaging [i.e. used as an additional sequence to the standard protocol study and not as a unique imaging series]; it is fast, requires no intravenous contrast and is non-invasive. The radiologist has to be aware of the potential pitfalls and limitations of the technique. In patients who cannot receive gadolinium-based contrast agents, DW MR imaging has the potential to be a reasonable alternative technique to contrast-enhanced imaging. We suggest the following strategy for evaluating DWI features of FLLs. We believe that most of the FLLs can be practically classified as benign or malignant by using this scheme
