OBJECTIVE To determine the film-retake rates and causes in digital radiography comparison to conventional X-rays method. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Radiology Department, Aga Khan University Hospital, Karachi, from January 2004 to December 2006. PATIENTS AND METHODS X-rays of different body parts, conducted during the year 2004, with conventional radiograph...

A set of modelled computed radiography (CR) systems are compared with a reference system. Calculations are performed, which compares the effective dose and a set of figures of merit corresponding to the image quality of both the modelled systems and the reference system. For a nodule with soft tissue corresponding, the signal-to-noise ratio, SNR, is found to decrease with increasing tube voltag...

INTRODUCTION Tumoral calcinosis is an uncommon disorder characterised by the deposition of calcium phosphate in periarticular tissues. The deposits are usually around large joints; but rarely can be found around small joints of hand and feet. CASE REPORT We present the case of 13 year old female with three years history of spontaneous, progressively increasing, painful swellings along right m...

Methods A 37-year-old female suffered from a road traffic accident while out of the car. Her mental status was clear. She had no history of hypertension and diabetes. On admission her vital signs were stable. Systolic blood pressure was 110 mmHg. Neurological examination was normal. Upper and lower extremity pulses were palpable with hand. Right upper extremity radiography showed fracture in ra...

PURPOSE The purpose of this study was to assess radiographer familiarity and preferences with digital radiography in four teaching hospitals and thereafter make recommendations in line with the migration from screen film to digital radiography. MATERIALS AND METHODS A questionnaire was designed to collect data from either qualified or student radiographers from four teaching hospitals. From t...

Volume 83, Number 10 www.aafp.org/afp American Family Physician 1203 A 61-year-old woman presented with a history of chronic pain and stiffness in multiple joints. She had morning stiffness in her hands, hips, and knees that gradually improved with activity. She did not report any foot pain or stiffness, fever, or rash. On examination she had swelling around the distal interphalangeal joints in...

The effectiveness of a positioning doll for radiography training (XPD) and acquiring the techniques of radiography was evaluated through performing radiography practice for the students in our school of radiological technologists and a questionnaire for radiological technologists. We made a ranking test composed of a five-grade evaluation system of the 39 students for the techniques of radiogra...

PURPOSE The purpose of this review is to evaluate the possibility of panoramic radiography as a national oral examination tool. MATERIALS AND METHODS This report was carried out by review of the literatures. RESULTS Panoramic radiography has sufficient diagnostic accuracy in dental caries, periodontal diseases, and other lesions. Also, the effective dose of panoramic radiography is lower th...

The present study introduces two quantitative parameters to compare the accuracy of ultrasonic C-scan testing and X-ray radiography methods in the damaged area detection under low-velocity impact in polymer-based composites. For this purpose, the hand lay-up technique of composite processing was employed to prepare the composite specimen. A composite specimen consisting of the glass fiber reinf...
