Purpose: To assess radiation dose reduction for abdominal computed tomography (CT) examinations with adaptive statistical iterative reconstruction (ASIR) technique. Materials and Methods: With institutional review board approval, retrospective of weight adapted CT exams were performed in 156 consecutive patients ASIR 66 filtered back projection (FBP) on a 64-slice MDCT. Patients categorized into 3 groups <60 kg (n = 42), 61 to 90 100), ≥91 80) weight-based adjustment automatic exposure...
Purpose: To assess radiation dose reduction and image quality for weight-based chest computed tomographic (CT) examination results reconstructed using adaptive statistical iterative reconstruction (ASIR) technique. Materials Methods: With local ethical committee approval, weight-adjusted CT examinations were performed ASIR in 98 patients filtered backprojection (FBP) 54 weight-matched on a 64-slice multidetector CT. Patients categorized into 3 groups: 60 kg or less (n = 32), 61 to 90 77), 91...
Purpose To compare visualization of subtle normal and abnormal findings at computed tomography (CT) the chest for diffuse lung disease with images reconstructed filtered back projection adaptive statistical iterative reconstruction (ASIR) techniques. Materials Methods In this HIPAA-compliant, institutional review board–approved study, 24 patients underwent 64-section multi–detector row CT evaluation disease. Scanning parameters included a pitch 0.984:1 120 kVp in thin-section mode, 2496...
OBJECTIVE. The objective of this study was to evaluate the image quality and diagnostic performance simulated low-dose MDCT examinations in patients with Crohn's disease.
To assess the prevalence of brown fat in patients with cancer, compare demographic characteristics those and without fat, correlate these mean maximum standardized uptake values fat.This case-control study was institutional review board approved HIPAA compliant. Informed consent waived. Reports 12 195 consecutive positron emission tomography/computed tomography examinations performed 6867 between January 2004 November 2008 were reviewed for documented fluorodeoxyglucose (FDG) (n = 298)....
The purpose of this study was to assess the role PET/CT in diagnosis pulmonary lymphangitic carcinomatosis.Integrated images 35 patients (15 men, 20 women; mean age, 64.5 years) with carcinomatosis confirmed at follow-up chest CT or histopathologic examination were analyzed retrospectively. Standardized uptake value based on body weight and initial injected activity measured affected lung, normal mediastinal blood pool. Two radiologists independently assessed abnormal PET lungs. Both...
Symptomatic bladder outlet obstruction and neurogenic are common conditions that frequently necessitate suprapubic insertion of a tube. The purpose this study was to describe an experience with minimally invasive imaging-guided percutaneous tube placement the clinical technical success complications encountered.A total 585 primary insertions 439 exchanges tubes were performed on 549 patients (469 men, 80 women; mean age, 66 years; range, 15-106 years). details (indication, type, size at...
Smoking is one of the strongest predictors attachment and bone loss. Smokers demonstrate reduced inflammatory clinical signs, which could be due to local vasoconstriction increased gingival epithelial thickness. The byproducts originating from tobacco oxidation modify characteristics progression periodontal disease. aim this study was investigate relationship between thickness marginal oral epithelium, sulcular bleeding, vascular caliber density microvessels in smokers nonsmokers with...
To assess imaging features of pericardial metastases on chest computed tomography (CT) scanning.This institutional review board-approved retrospective study included 60 patients (24 men, 36 women; mean age, 62 [SD, 13] years). All CT scans for these were reviewed independently presence effusion, irregularity, enhancement, nodules, and masses coexistent cardiac lesions (metastasis). Location nodules irregularity type location primary malignancy recorded.Of with metastasis, 54 (90%) had...
To assess the effects of radiation dose reduction in chest CT using a weight-based adjustment automatic exposure control (AEC) technique.With Institutional Review Board Approval, 60 patients (mean age, 59.1 years; M:F = 35:25) and 57 weight-matched 52.3 years, 25:32) were scanned weight-adjusted AEC non-weight-adjusted AEC, respectively on 64-slice multidetector with 0.984:1 pitch, 0.5 second rotation time, 40 mm table feed/rotation, 2.5 section thickness. Patients categorized into 3 weight...
Purpose: To determine the effects of arm position on appearance structures in upper chest as seen computed tomography (CT), such clavicular angle, course axillary vessels, pectoralis major muscle, and bicipital groove. Materials Methods: The study consisted 52 CT examinations (32 from men 20 women; mean [SD] age, 64 [20] years) performed with 1 or both arms at above shoulder (n = 44 arms) by side body 60 arms). Three radiologists assessed randomized for specific anatomical including...
Correction of gingival recession (GR) involves eliminating the cause and it often requires surgical correction. Subepithelial connective tissue graft (SCTG) technique by Langer provides excellent esthetics is considered most predictable in obtaining marginal coverage. However, requirement a second procedure for harvesting CTG remote from planned site coverage increases chances postoperative infection. There also limitation amount that can be harvested an increased operative time contributing...
Periodontal disease is a multifactorial resulting into pocket formation, recession, and bone loss. The ultimate goal of periodontal therapy to halt the progression regeneration lost periodontal-supporting tissues. by definition involves cementum, alveolar bone, ligament. Conventional surgical approaches such as open flap debridement have been found efficient in establishment improved form architecture but limited potential restoring aim use guided-tissue membranes grafts achieve instead...
A 23-year-old woman with persistent latent HIV infection on Highly Active Anti-Retroviral Treatment (HAART) since 2009 was admitted a 3-week history of progressive and severe imbalance walking. Gradually, she developed total inability to walk or stand without support. She dysarthria for one week had excessive somnolence. There no fever, headache, vomiting seizures. reported gradual loss weight nearly 5 kilograms (kgs) in the last 2 years. alcohol, substance abuse any other recent drug...
Introduction: Gingival epithelium is made up of stratified squamous consisting specific cytokeratins (CKs), as intermediate filament proteins the cytoskeleton. These CKs are involved in transduction signals and transport nutrients from inside to outside cell vice versa. Their expression varies diseased inflammatory conditions can serve prognostic markers various diseases.Objectives: The objective study evaluate alteration CK pattern topographical distribution individual among smokers...
