Accuracy of panoramic radiography in diagnosing maxillary sinus-root relationship: A systematic review and meta-analysis. Angle Orthod. 2018 Sep 04;: Authors: Sun W, Xia K, Tang L, Liu C, Zou L, Liu J Abstract OBJECTIVE: To investigate the accuracy of panoramic radiography (PR) in diagnosing maxillary sinus-root relationships (SRRs). MATERIALS AND METHODS: PubMed, EMBASE, CENTRAL, Web of Science, ScienceDirect, CBM, Baidu Scholar, and SIGLE were searched. The studies comparing the diagnostic accuracy of PR and computed tomography/cone-beam computed tomography (CT/CBCT) for SRR were included. RESULTS: Eleven studies were included. Meta-analyses showed that, for type I SRR, PR had the highest specificity, positive likelihood ratio (+LR), diagnostic odds ratio (DOR), and area under the curve (AUC), with a high sensitivity and a low negative LR (-LR). For type IV, PR had a high DOR and AUC, with the highest sensitivity but a low +LR, the lowest -LR, and the lowest specificity. For type II, PR had the lowest AUC, with a low sensitivity, +LR, and DOR and a high -LR. For type III, PR had the lowest sensitivity, +LR, and DOR and the highest -LR. The distance from root tips to the maxillary sinus floor on PR was significantly longer (mean difference: -1.88 mm; 95% confidence interval: -2.19 to -1.57; P
ConclusionsThe absorbed dose within all radiosensitive tissues varied considerably in relation to examination type, x-ray unit, clinical settings, and patient age. The mean doses were smaller when using 2 (bilateral) 4 × 4 cm volumes than with use of one 14 × 5 cm volume.
ConclusionAlthough rare, osteoid osteoma may occur in the hallux. Even if the patient age, pain pattern, and radiographic findings do not exactly meet the classical definitions for osteoid osteoma, this tumor should always be included in the differential diagnosis list in patients presenting with foot pain.
Polydioxanone (PPDO) is a resorbable polymer that has been shown to be effective resorbable inferior vena cava filters (IVCF) in preventing pulmonary embolism (PE). However, PPDO is radiolucent with no intrinsic capability for radiographic visualization. Here, we synthesized bismuth nanoparticles (BiNPs) and infused unto PPDO, making it visible by x-ray and computed tomography (CT). This enhanced radiopacity will allow placement accuracy during device implantation and continuous monitoring of the structural integrity of the device to check for fracture or device failure post implantation.

To quantify the frequency and accuracy of inferior vena cava filter reporting practices on plain radiography and computed tomography examinations with attention to retrievability and device brand. Improved reporting may encourage appropriate anticoagulation or facilitate filter retrieval.
This study aimed to investigate a series of patients diagnosed with LTBI during screening before immunosuppressive therapy, describing how the use of diagnostic tests and treatment evolved over time. This retrospective cohort study included all individuals diagnosed with LTBI during screening before intended immunosuppressive therapy in a tertiary care hospital between January 2000 and December 2017. Evidence for LTBI, including history, tuberculin skin test (TST), QuantiFERON (QFT) result and suggestive lesions on chest radiography (CXR), and CT scan if available, was analyzed. The study included 295 individuals with LTBI...
Conclusion Interrater agreement on CT findings was substantial except on skull base involvement. CT correctly predicted site of tumor origin in up to 74% of subjects. CT was not sensitive for diagnosing skull base involvement but had substantial-to-near perfect agreement with pathologic tumor staging. CT is a useful but albeit limited adjunct for tumor localization and surgical planning for sinonasal IP.

AbstractMandibular fractures are among the most common maxillofacial fractures observed in emergency rooms and are mainly caused by road accidents. The clinical features of mandibular fractures include malocclusion and loss of mandibular function. Panoramic radiography is usually limited to isolated lesions, whereas computed tomography is the tool of choice for all other facial traumatic events. No reference standard classification system for the different types of mandibular fractures is defined. Therapeutic options include a conservative approach or surgical treatment based on the anatomic area and the severity of fractu...
Conclusions3-dimensional printing technique-assisted arthroscopic bone graft and fixation of scaphoid nonunion constitute an effective and accurate clinical treatment option.
ConclusionsThe novel success scale for evaluating alveolar cleft repair using CBCT takes into consideration all dimensions of the bony bridge. Future application is necessary for validation of its potential value.
