Chest CT Scan at Radiation Dose of a Posteroanterior and Lateral Chest Radiograph Series

Anteroposterior chest radiograph vs. chest CT scan in early detection of pneumothorax in trauma patients

Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for bette...

Clinical Value of Low Dose CT- Scan in Pediatric Chest Diseases: Adequacy Assessment

Background Radiation dose about 400 times that of standard thoracic computed tomography (CT) in comparison with chest X- ray resulting in different approaches to decrease radiation dose have been established in the last few years to prevent possible side effects especially in children, such as low dose protocols. The aim of this study was assessment of clinical v...

Comparing the Diagnostic Power of Chest CT Scan and RT-PCR in Diagnosis of COVID-19

Background and purpose: Proper diagnosis of patients with COVID-19 is one of the challenges in medical centers. RT-PCR is the standard and reference test in diagnosis of patients with COVID-19. This study aimed at accelerating the correct diagnosis of COVID-19 and the diagnostic power of chest CT scan and RT-PCR. Materials and methods: This study was performed in 569 patients with COVID-19 adm...

Image Registration for a Series of Chest Radiograph Images

To investigate the effect of treatment, a study on the progress of an MTB patient is carried out. One approach is to compare a series of chest radiographs taken at three different time points. For each radiograph a subset of the image representing the diseased area is derived, and henceforth monitoring is defined as the activity of comparing the three corresponding subset image. The elements of...
