Is cone beam computed tomography accurate for post-operative evaluation of implants? an in vitro study

ConclusionConventional radiographs showed the highest accuracy for bone/implant interface diagnosis. However, CBCT scans (i-CAT 0.125 mm voxel), if available or if performed for pre-surgical assessment of another implant site, may provide similar accuracy.

Authors: Wen SC, Fu JH, Wang HL Abstract The aim of this study was to compare the amount of radiographic horizontal buccal bone thickness (BBT) at implant dehiscence defects grafted with the sandwich bone augmentation (SBA) and modified sandwich bone augmentation (MSBA) techniques. Compared to the SBA technique, the MSBA approach involved an additional outer layer of deproteinized bovine bone mineral (DBBM) to maintain the space for bone regeneration for longer periods. A total of 19 patients, each with a buccal implant dehiscence defect, were recruited. The control group was treated with SBA technique (n = 10), wh...

CONCLUSIONS: Both techniques achieved excellent results and no differences were observed between prostheses supported by one to two 5 or 6 mm long implants vs 10 mm long in posterior atrophic maxillae up to 3 years after loading; therefore it is up to clinicians to decide which procedure to use, although longer follow-ups with larger patient populations are needed to better understand if one of these procedures could be more effective in the long-term. Conflict of interest statement: this study was partially supported by Zimmer Biomet. However, data property belonged to the authors, and by no means did the manufacturer int...

We report a case of a 49 year-old female who presented with a mass on the left side of the floor of the mouth. She was complaining of neck pain for the last 2-3 days and had noticed the mass growing in size and becoming tender to palpation. There was no exacerbation of pain during eating, drinking or opening of mouth. A multidetector computed tomography scan was made. The radiographic examination revealed a mostly well-defined hypodense area suggestive of mucocele (ranula), which was thought to be corroborated by the clinical findings. The treatment of choice was the complete excision of the mucocele and the left submandib...

Ashu S Bhalla, A Das, P Naranje, A Goyal, R Guleria, Gopi C KhilnaniIndian Journal of Radiology and Imaging 2017 27(4):380-388 The second part of the review discusses the role of different existing imaging modalities in the evaluation of thoracic sarcoidosis, including chest radiograph, computed tomography, magnetic resonance imaging, endobronchial ultrasound, and positron emission tomography. While summarizing the advantages and pitfalls of each imaging modality, the authors propose imaging recommendations and an algorithm to be followed in the evaluation of clinically suspected case of sarcoidosis in tuberculosis-endemic regions.

Conclusion Our data indicate that 131I therapy is highly effective in the treatment of lymph node metastases from papillary thyroid carcinoma; patients with a small size of metastatic lymph node, younger patients, those with lower thyroglobulin levels, and patients with lymph node metastases detectable on the first postablative 131I Rx-WBS and single-photon emission computed tomography–computed tomography showed a good response to radioiodine ablation therapy.

ABSTRACT Background and objectiveThe diagnostic classification of ‘possible idiopathic pulmonary fibrosis (posIPF)’ is characterized by a radiological pattern of inconsistent usual interstitial pneumonia (UIP) on high‐resolution computed tomography (HRCT) scan and a UIP pattern in surgical lung biopsy (SLB). The evidence base to guide treatment for patients with posIPF is lacking; the clinician must choose between observation, treatment with immunomodulatory agents or anti‐fibrotic agents. MethodsTo evaluate outcomes of immunomodulatory treatment, a multicentre cohort of 59 posIPF patients treated with pred...

Introduction: Sarcoidosis is a multiorgan granulomatous disease of unknown etiology. 18F-fluorodeoxyglucosis positron emission tomography computed tomography (18F-FDG PET/CT) has been reported useful in the estimation of sarcoidosis activity and extent.Aim: To investigate the role of 18F-FDG PET/CT in the evaluation of intrathoracic active disease and its relationship to functional and clinical findings in pulmonary sarcoidosis patients.Material and methods: Sarcoidosis patients referred to our department between 2011 and 2016 were prospectively investigated by chest X-ray, CT, pulmonary function testing and 18F-FDG PET/CT...

Conclusions: We believe this is the first study to demonstrate the prognostic value of ALP and albumin in predicting decline in pulmonary sarcoidosis. Interestingly, MRC breathlessness score outperformed baseline DLCO in this model. We plan to remove confounders such as treatment and validate our model in a second cohort of patients presenting to a separate clinic. Further validation of this model may assist in decisions of when to initiate treatment.
