Cone beam computed tomographic assessment of mandibular condyle in Kennedy class I patients

ConclusionLoss of posterior teeth is accompanied by significant decrease in condyle height and increase in condyle width with no change in the total condyle volume or antero-posterior dimensions.

This study involved spontaneous ICH patients of two cohorts who underwent baseline CT scan within 6  h after ICH onset and follow-up CT scan within 24 h after initial CT scan. We determined the critical value of the minimal CT attenuation value via retrospective analysis of the data from a derivation cohort. Then, a prospective study on the validation cohort of three clinical centers was perform ed for determining the association between the minimal CT attenuation value and hematoma expansion as well as poor outcome (modified Rankin Scale scores >  3) at 90 days by using univariate and multi...

Authors: Krishan A, Mittal D Abstract Our proposed research technique intends to provide an effective liver magnetic resonance imaging (MRI) and computed tomography (CT) scan image classification which would play a significant role in medical dataset especially in feature selection and classification. There are a number of existing research works classifying the liver tumor disease. Early detection of liver tumor will help the patients to get cured rapidly. Our proposed research focuses on the classification of medical images with respect to the classification technique artificial neural network (ANN) to classify a...

Authors: Marques B, Couto J, Lemos MC, Rodrigues F Abstract Juxtaglomerular tumours are rare causes of secondary hypertension. They typically present with difficult-to-manage hypertension, hypokalemia, hyperreninemia and secondary hyperaldosteronism. The authors describe a clinical case of a 45 years old female patient, with personal history of difficult-to-manage hypertension and hypokalemia since age 35, medicated with four types of anti-hypertensive agents. An analytical study was performed, which revealed secondary hyperaldosteronism [aldosterone 44.3 ng/dL (4 - 28 ng/dL), renin> 1000 mIU/mL (4.4 - 46.2 mIU/...

AbstractRenal imaging is an essential investigative tool and preliminary task for determining a suitable sanative option for the treatment of kidney cancer. In recent decades, with the increasing usage of abdominal imaging, there is an upsurge in the number of adrenal incidentalomas. Among these accidentally revealed lesions, most of them are complex that warrant immediate aggressive treatment planning due to their malignant potential. The guidelines given by the American Urological Association (AUA), American College of Radiology (ACR), and European Association of Urology (EAU) vary concerning the use of ideal preliminary...

AbstractPurpose of ReviewPositron emission tomography (PET) combined with computed tomography (CT) has proven useful as a cancer screening technique in patients with inflammatory myopathy, mainly dermatomyositis. In this review, we focus on advances in this direction and other potential applications of PET/CT in patients with inflammatory myopathy.Recent FindingsCancer screening by PET/CT seems suitable and cost-effective in patients with myositis. It has also shown value as a hybrid technique for diagnosing myositis versus controls and could be of interest for differentiating between polymyositis and sporadic inclusion bo...

In this study, we proposed a method to determine the frequency response of a filter kernel and verify its validity. Two clinical CT scanners were used to derive the filter kernel. The MTF was obtained and subsequently separated to the MTF of the scanner system and MTFA. Using the relational formula of the filter kernel and MTFA, we calculated the frequency response of the filter kernel. To verify the calculated result, we measured the noise power spectrum (NPS). Additionally, the filter kernel was calculated using the relational formula of the filter kernel and NPS. In both CT scanners, the filter kernels calculated by the...
