An analysis of effective dose optimization and its impact on image quality and diagnostic efficacy relating to dental cone beam computed tomography (CBCT)

An analysis of effective dose optimization and its impact on image quality and diagnostic efficacy relating to dental cone beam computed tomography (CBCT) Swiss Dent J. 2018 Mar 28;128(4):297-316 Authors: McGuigan MB, Duncan HF, Horner K Abstract The potential of high resolution, three-dimensional (3D) images which overcome limitations such as superimposition and anatomical noise of two-dimensional (2D) conventional imaging, has made cone beam computed tomography (CBCT) an increasingly popular imaging modality in many dental applications. It is in light of the increasingly prevalent use of CBCT, particularly in a primary dental care setting, that the goal of this review is to investigate what evidence-based guidance is available to the clinician to justify and reduce radiation risk of this higher dose imaging modality while maintaining diagnostically acceptable images. To this end, the literature on radiation dose and related patient risk was comprehensively investigated, before an analysis of the ways in which dose can be optimized and the implications that optimization has on image quality was discussed. Finally, although it is accepted that CBCT has the potential to improve diagnosis, it is uncertain if its use has positive ramifications on issues of diagnostic efficacy, including clinical decision-making and patient outcome. In order to investigate these issues, the levels of evidence of the existing studies and their validity were assessed. On review...

ConclusionPET/CT-guided molecular biopsy using Ga-68 labelled radiotracers is feasible and can be performed safely and accurately with a high-diagnostic yield. It is helpful in accurately staging the disease when tracer-avid isolated distant lesion evident on imaging and highly practical in patients with previous inconclusive sampling.

Discussion The anterior cruciate ligament (ACL) “is an intra-articular but extrasynovial collagenous structure with limited healing capacity that originates in the posteromedial aspect of the lateral femoral condyle and crosses into anteromedially to insert anterior into the intercondylar eminence of tibial articular surface.” It plays an important part as a mechanoreceptor particularly as a proprioceptor. Its main role is to prevent excessive anterior tibial translation, limits varus/valgus stress when the knee is in full extension and some rotary movements of the knee. There are ~120,000 surgeries per year m...

In Reply We agree with Popkirov that left atrial volume is a better marker of incident atrial fibrillation than atrial diameter; however, we did not have these data available at all of the sites participating in the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial. Recently completed and ongoing studies will help determine if our observation has a clinical role and may provide additional data on left atrial size and function. Once all of these data are available, guidelines committees will likely make recommendat...

To the Editor In a secondary analysis of the New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial Versus ASA to Prevent Embolism in Embolic Stroke of Undetermined Source trial, Healey and colleagues determined that for patients with embolic stroke of undetermined source and left atrial enlargement rivaroxaban treatment was associated with a 74% reduction in recurrent stroke. The authors suggest that left atrial enlargement could become a new determinant in secondary stroke prevention.

Postoperative pancreatic fistula remains an unsolved challenge after pancreatoduodenectomy. Important in this regard is the presence of a soft pancreatic texture which is a major risk factor. Advances in machine learning and texture analysis of medical images allow identification of features of parenchyma that are invisible to the human eye. The aim of this study was to investigate the potential of machine learning to predict postoperative pancreatic fistula based on preoperative, non-contrast-enhanced computed tomography.

AbstractBackgroundMost bariatric treatments employ gastric volume reduction. However, there has been no appropriate tool that could assess the anatomical factors of the stomach, and few studies have investigated proper stomach measurement for bariatric treatment. Thus, this study aimed to objectively estimate the individual stomach using three-dimensional (3D) computed tomography (CT) gastrography for the possible acquisition of information that could facilitate bariatric treatment and to validate these factors.MethodsA total of 100 consecutive patients with different degrees of obesity who underwent 3D CT gastrography wer...

The objectives of this systematic review were to investigate the role of HRM in the assessment of SSc-associated upper GI involvement and to evaluate the correlation between HRM abnormalities and clinical characteristics and the effects of therapeutic interventions on HRM findings. Fifteen articles were included. Most (11/15) studies were of very good or good quality. Most studies assessed correlations between esophageal symptoms and esophageal dysmotility. Two studies assessed the effectiveness of buspirone and reported HRM findings. Studies assessing upper GI symptoms using validated questionnaires, such as the Universit...
