This study evaluated the frequency in which a hip dislocation is first diagnosed by computed tomography (CT) scan. A retrospective review was conducted of orthopaedic trauma patients presenting with hip dislocation to a Level 1 trauma center over three years. We recorded whether the patient first received pelvic radiograph (PXR) or CT scan of the pelvis, if the patient underwent closed reduction of the hip prior to CT scan, and if repeat pelvis CT scan was done. Of 83 hip dislocations, 64 patients were sent to CT scanner dislocated; 19 patients first had PXR and underwent closed reduction of the hip prior to CT scan. By ob...

This study aimed to evaluate the prevalence of internal symmetry (the number and morphology of root canals) in the mandibular incisors using cone beam computed tomography (CBCT). A total of 302 CBCT scans involving 1,208 mandibular incisors were evaluated using the Vertucci's classification regarding the number and configuration of root canals. The central mandibular incisors exhibited two root canals in 22.6% of patients and lateral incisors in 24.3% of patients. Most teeth (76.4%) had a type I configuration (a single root canal, 1-1), 21.7% had type II (2-1), 1.1% had type V (1-2), and 0.8% had type IV (2-2). Teeth with ...

By STEPHEN BORSTELMANN, MD Occasionally, you get handed a question you know little about, but it’s clear you need to know more.  Like most of us these days, I was chatting with my colleagues about the novel coronavirus. It goes by several names: SARS-CoV-2, 2019-nCoV or COVID-19 but I’ll just call it COVID.  Declared a pandemic on March 12, 2020 by the World Health Organization (WHO), COVID is diagnosed by laboratory test – PCR.  The early PCR test used in Wuhan was apparently low sensitivity (30-60%), lengthy to run (days), and in short supply.  As CT scanning was relatively availa...

Conclusion: We recommend radiography or cone-beam computed tomography (CBCT) scanning for individual patients judged to require a cross-sectional image after reading of a panoramic X-ray image and a conventional intraoral radiological image. Various steps should be taken to raise awareness of these recommendations among clinicians and the public, and K-CIG should be regularly reviewed and revised. PMID: 32206620 [PubMed]

AbstractPurposeMandibular condyle development can be evaluated with radiographic evaluation of subchondral cortical bone. The aim of this study is to investigate mandibular condyle cortication (MCC), articular eminence cortication (AEC) and mandibular cortical index (MCI) according to age and gender on CBCT, and relationship between each other.MethodsCBCT scans of 520 patients (312 male and 208 female, age range 7 –84) were retrospectively investigated to evaluate MCC, AEC and MCI. MCC and AEC were examined in sagittal section and MCI in panoramic reformatted image. MCC and AEC were classified as Type I, Type II and ...

AbstractPurpose of ReviewThis review discusses imaging modalities for fracture repair assessment, with an emphasis on pragmatic clinical and translational use, best practices for implementation, and challenges and opportunities for continuing research.Recent FindingsSemiquantitative radiographic union scoring remains the clinical gold standard, but has questionable reliability as a surrogate indicator of structural bone healing, particularly in early-stage, complex, or compromised healing scenarios. Alternatively, computed tomography (CT) scanning enables quantitative assessment of callus morphometry and mechanics through ...

CONCLUSION: Excessive overscanning was due to inconsistent technique in capturing CT-KUB scans. Before this audit, the superior limit of CT-KUB scans had not been formally clarified at our trust. By successfully standardising the process with a reproducible method, the overscan target was comfortably met. Therefore, patient dose was minimised without compromising scan quality. ADVANCES IN KNOWLEDGE: This audit has successfully shown a feasible standardised protocol for CT-KUB investigations which can be used to minimise overscanning of patients.

The advent of the CT scanner in the early 1970s removed much, if not all, of the morbidity and discomfort previously associated with diagnostic imaging studies. Throughout the 1970s and 1980s, advances in CT technology allowed radiologists to scan “better and faster.” The professional fee for reading a CT study was higher than for reading a radiograph, an uncontroversial policy. But estimating the technical fee for using CT (and later MR) raised problems that would persist for at least 30 years.

CONCLUSION: The current literature suggests that CT has several advantages over radiographs for preoperative planning of THA including more accurate planning of implant size, component alignment, and postoperative leg length. It is also superior to x-ray in identifying extraarticular hip deformities using the minimum effective dose for CT and the minimum scan length required by templating software. The radiation can be reduced to values similar to radiography. PMID: 32196566 [PubMed - as supplied by publisher]

The American College of Radiology (ACR) is urging radiologists to steer clear of CT scans and chest radiographs (CXR) as their first line of diagnostic defense of COVID-19 diagnosis and treatment, according to a recently issued statement. With the unpredictability of available testing kits and early reports of test sensitivity from China, health care providers are turning to imaging devices to detect infection symptoms. However, the ACR encourages healthcare providers to stick to viral testing, and explains why CT and CXR should be used at a minimum. Here are some takeaways from the official recommendation:The results from...
