Diagnostic Certainty

Aim: There is an increasing incidence of hip fracture with associated morbidity and mortality making accurate and timely diagnosis essential. The aim of this study was to compare computed tomography (CT) and magnetic resonance imaging (MRI) to ascertain the optimum second-line investigation in cases where plain radiograph is not diagnostic. Material and Methods: Using the radiology information system, a total of 168 patients were identified with the suspected occult neck of femur fractures over 24 months who had undergone CT or MRI as second-line investigation. All relevant imaging was reviewed and diagnosis, any third-line or follow-up imaging was documented. Results: About 16% of patients undergoing CT as second-line test had proven originally occult femoral neck fractures on plain radiograph compared with 13% of those having MRI. About 13% of patients underwent MRI following CT and in 1/13 case MRI detected an occult fracture that had not been detected on CT. The remaining 11 patients were either negative or MRI proved CT suspicions of fracture when extra diagnostic certainty was requested by the surgeons. CT detected more non femoral pelvic fractures 47% versus 37%. Conclusion: CT and MRI are comparable at detecting occult femoral neck fractures. Given the increased availability, improved patient tolerance and speed of CT imaging, we advocate its use as the main second-line imaging modality. MRI remains a valuable problem-solving tool in a select few cases following review with a musculoskeletal radiologist.

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.
