Despite progress in noninvasive imaging with computed tomography and magnetic resonance imaging, conventional angiography still contributes to the diagnostic workup of oncologic and other diseases. Arteriography can reveal tumors not evident on cross-sectional imaging, in addition to defining aberrant or unexpected arterial supply to targeted lesions. This additional and potentially unanticipated information can alter management decisions during interventional procedures.

The authors presented the computed tomography and magnetic resonance imaging appearances of a painful os cuboideum secundarium. To the authors' knowledge, this is the first report of the cross-sectional imaging appearance of this condition, and serves to underline the utility of computed tomography and magnetic resonance imaging in the investigation of foot pain.

Introduction Nasopharyngeal carcinoma is a rare neoplasm in the UK. The current gold standard for detection is endoscopic examination under anaesthesia of the nasopharynx with biopsy. Many clinicians are now advocating cross-sectional imaging as the primary investigation. The objective of this study is to evaluate the role of cross-sectional imaging in detecting nasopharyngeal carcinoma and ultimately to avoid unnecessary biopsy. Material and methods This is a retrospective uncontrolled case series review of patients who were investigated for suspected nasopharyngeal carcinoma between 2009 and 2017 at York Teaching Hospital NHS Foundation Trust. At present, any suspected nasopharyngeal carcinoma requires biopsy. Search terms used were ‘endoscopic biopsy of nasopharynx’, ‘endoscopic examination + biopsy nasopharynx’. The main outcome measures are reported histological and radiological features of malignancy. Only patients who had imaging prior to the biopsy were included. Results A total of 144 patients had endoscopic examination under anaesthesia of the nasopharynx with biopsy. Approximately one-third of these patients had cross-sectional imaging before the biopsy. The study revealed that magnetic resonance imaging had 100% sensitivity and 84% specificity; however, the endoscopic examination under anaesthesia and biopsy had only 88% sensitivity. This is due to a negative histological finding despite radiological characteristics of nasopharyngeal carcinoma in some patients. However, the specificity was 100%. Conclusion The study supports magnetic resonance imaging as the primary investigation in patients with suspected nasopharyngeal carcinoma followed by endoscopic examination under anaesthesia and biopsy in cases with suspicious findings on imaging only.

The increasing availability of cross-sectional imaging, incredibly magnetic resonance imaging, detects ndings in the patient's scan unrelated to the reason the scan is initially acquired. These ndings refer to the so-called incidental ndings mentioned in the radiology report as "Note made of" without any good impression about their clinical signicance or further management. This type of report leads to anxiety among patients. The radiologist is the rst person to encounter these incidental ndings. Therefore, it is an essential duty of the radiologist to communicate to the clinician about the signicance and urgency/non-urgency of these ndings so that clinicians can decide timely appropriate management. Therefore, this review discusses the prevalence and spectrum of these incidental ndings and the available guidelines for their management.

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.

Tarsometatarsal Joint

Background Fibrocartilaginous coalition of the third tarsometatarsal joint has been indicated as an extremely rare form of tarsal coalition in the radiological literature, and most articles concerned with tarsal coalition do not mention involvement of this joint. Only two reports written in the English language that approach this subject were found, an orthopedic report and an anthropological report. Purpose To evaluate the prevalence of this finding and discuss and illustrate the radiological characteristics of this coalition. Material and Methods A retrospective analysis of 614 computed tomography or magnetic resonance imaging scans of the ankle and/or foot, acquired at a health service within a period of three months, was performed to assess the prevalence of this coalition. Results Of the examinations characterized as valid for analysis for the purposes of the study, 17 cases compatible with fibrocartilaginous coalition of the third tarsometatarsal joint were found, thus indicating an involvement of approximately 2.97% of the examined feet. Conclusion Our radiological findings are typical, and the prevalence found in this study was statistically significant, being similar to that described in the anthropological report (3.2%–6.8%).
