Introduction: Recently, the use of nanoparticles has increased for many purpose in medicine. One of these is using the nano particles in shields structure to protect sensitive organs such as breast which placed inside the field of chest CT scan and receives high dose. The aim of this study was the use of nano Bi2O3 to making shield for protection breast in chest CT examination ...

The appearances of pathological changes of bone can be various. Determination of apparent bone mineral density is commonly used for diagnosing bone pathological conditions. However, in the last years the structural changes of trabecular bone have received more attention because bone densitometry alone cannot explain all variation in bone strength. The rapid progress in high resolution 3D micro ...

background: this study set out to evaluate the utility of cerebrovascular virtual non-contrast (vnc) scans. materials and methods: conventional non-contrast (cnc) and dual-energy computed tomography angiography (de-cta) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...

Aim: To evaluate the role of high-resolution Computer tomography imaging in management COVID-19. Study design: Prospective study Place and duration study: Jinnah Postgraduate Medical Centre Karachi from 1st December 2021 to 31st May 2022. Methodology: One hundred patients suspected be suffering COVID-19 were enrolled. All underwent Reverse transcriptase-based polymerase chain reaction tests (RT...

We describe a patient with dysphagia. The results of endoscopy, CT scan and echoendoscopy were normal. High-resolution manometry (HRM) showed esogastric junction dysfunction and hypercontractile peristaltic disorder. These HRM abnormalities completely disappeared after pneumatic esophageal dilatation. We discuss the treatment options and recovery of peristalsis after balloon dilatation.

A patient presented with a painful third nerve palsy. This resolved spontaneously, but recurred several months later. At his second presentation carotid angiography gave normal results, but a high resolution CT scan showed a tumour in the right parasellar region. The serum prolactin was raised at over 22,000 millimicrons/, showing this to be a prolactinoma.

Many cases in which the skin complication are caused by increased exposure dose to skin by interventional radiology (IVR) are reported. Therefore, the decrease of patient exposure dose at IVR is important. Patient exposure dose by using IVR-computed tomography (CT) unit is defined as the sum of exposure dose from both angiography and CT scanner. The dose decrease with the CT device was examined...

This case report describes a patient with Swyer-James-MacLeod Syndrome (SJMS) in an adult male diagnosed on the basis of findings on X-ray chest, high resolution CT (HRCT) of chest and radionuclide perfusion lung scan. This rare syndrome is considered to be an acquired disease due to repeated pneumonias in early childhood.
