ABSTRACTBackground:Positron emission tomography (PET) and single photon emission computed tomography (SPECT) brain imaging are widely used as diagnostic tools for suspected dementia but no studies have directly compared participant views of the two procedures. We used a range of methods to explore preferences for PET and SPECT.Methods:Patients and controls (and accompanying carers) completed questionnaires immediately after undergoing PET and SPECT brain scans. Pulse rate data were collected during each scan. Scan attributes were prioritized using a card sorting exercise; carers and controls a

Recent studies have highlighted that chest CT scans are crucial for accurately diagnosing COVID-19. However, in rural areas of Indonesia, people may have difficulty assessing CT scans, leading to increased undetected cases. To address this issue, we investigated whether chest X-rays (CXR) could replace CT scans in diagnosing COVID-19 patients. A diagnostic cross-sectional-based study was conducted at Fatmawati General Hospital from January to September 2021.

Producing high-quality CT scans is crucial for accurately interpreting images and obtaining maximum diagnostic information. However, it usually comes at the cost of increased radiation exposure for the patient. Therefore, it's essential to evaluate CT scan image quality to ensure that it provides maximum information for diagnostic purposes while keeping the radiation dose received by the patient as low as possible. Several parameters can be used to evaluate the quality of CT scan images, such as accuracy, linearity, uniformity of the CT number, and high contrast resolution (spatial resolution)

Abstract Computed tomography (CT) scan is currently the most irradiating radio diagnostic procedure for the patients.

HIGHLIGHTS1. Ovarian tumors diagnostic value has been determined using the tools on contrast-enhanced abdominal CT Scan2. The tools including primary finding like mass size, septation, solid component, and additional finding such as ascites, peritoneal implants, lymph node enlargement3. Most tumors were ovarian malignant tumors according to their histopathological results 4. Contrast-enhanced abdominal CT Scan of ovarian tumors evaluated by the tools gave better and more reliable diagnostic value than without using the toolsABSTRACTObjectives: The purpose of this study was to determine the dia

229 Background: Wide IOV has been reported for CT-based TVD during radiotherapy planning for pancreatic cancer (Yamazaki, Anticancer Research 27: 2965-2972, 2007). PET-CT has been successfully incorporated into treatment planning in other tumour sites and has been shown to reduce IOV, but no study has looked at its role in pancreatic radiotherapy. Methods: Six radiation oncologists from 6 oncology centers in the UK were asked to outline GTVs in two cases with pancreatic head tumors. DICOM data set of planning CT, diagnostic CT and FDG-PET-CT scans were made available. GTV was first outlined us

99mTc-dimercaptosuccinic acid (DMSA) scintigraphy is currently the method of choice for assessing renal scarring in children, but it is not established whether conducting the scan as a single photon emission tomography combined with low-dose CT (SPECT/ldCT) scan provides additional diagnostic benefits when compared to conventional planar scintigraphy. In the present study, we evaluated the interrater reliability of DMSA SPECT/ldCT vs. planar DMSA scintigraphy for diagnosing renal scarring.

Optimization of medical exposure seeks to keep the dose given to the patient as low as possible. In diagnostic and interventional radiology activities, optimization focuses on low doses and ensures sufficient image quality for diagnostic purposes. Implementation of medical exposure optimization can be evaluated by applying the Diagnostic Reference Level (DRL). Indonesia set DRL values for CT Scan and General Radiography in 2021. This study monitored efforts to optimize medical exposure nationally by comparing the annual dose profile with the Indonesian DRL (I-DRL) and I-DRL against the regiona

Background: CT scans produce the largest dose of radiation compared to other radiology modalities. The parameters for measuring the amount of radiation dose from the CT Scan aircraft are the Computed Tomography Dose Index (CTDI) and the Dose Lenght Product (DLP). One form of Bapeten supervision in controlling radiation protection is to optimize the Diagnostic Raference Level (DRL).

Introduction: Computed tomography (CT) pan-scans have become increasingly commonplace as part of the initial diagnostic workup for patients sustaining traumatic injuries. They have proven effective in improving diagnostic accuracy in those with high-energy mechanisms of injury. However, the utility of pan-scans in the geriatric population sustaining low-energy traumatic injuries remains unproven. Methods: A retrospective review was conducted of patients who sustained a fragility fracture at a level-1 trauma center over a 15-month period.
