The cost of perfection: An investigation into the unnecessary rejection of clinically acceptable lateral wrist imaging.

Introduction: This study illustrates image rejection rates of the lateral wrist x-ray projection at a large, public teaching hospital. Rejected images were evaluated to determine the number of images that needed to be repeated based on the clinical indication. This study highlights the difference in subjective image-repeat decision-making skills existing between radiologists, experienced radiographers and junior radiographers.

Pre-operative templating for total hip arthroplasty: How does radiographic technique and calibration marker placement affect image magnification?

Introduction: Pre-operative templating using digital radiography is an effective method of planning for total hip arthroplasty (THA) and requires a generalised fixed magnification factor (MF) or external calibration markers (ECM). The effect on image magnification when changing source-to-image distance (SID), object-to-image distance (OID) and different imaging conditions is not well described. This study aims to quantify the range of effects manipulation of radiographic parameters can have on image magnification across different body habitus and imaging conditions.

An evaluation of the effect of tube potential on clinical image quality using direct digital detectors for pelvis and lumbar spine radiographs.

Introduction: High kVp techniques, 15% or 10-kVp rules, are well-known dose reduction methods. Traditionally, the use of high tube potential (i.e.

Carbon dioxide CT angiography during endovascular treatment of bilateral common iliac disease with angio-CT utilisation.

This paper presents the application of carbon dioxide for CT imaging during an endovascular procedure to help characterise unexpected bilateral common iliac artery stenosis utilising an angio-CT system, confirming its application in interventional radiology while maintaining sterility. A 78 year old male was referred to the Radiology Interventional Suite with left lower limb rest pain. On imaging via digital subtraction angiography and CT utilising both iodinated contrast and carbon-dioxide (CO ), endovascular treatment of bilateral CIA stenosis was performed with good clinical result.
