Objectives:
To ascertain clinicians' knowledge of their patients when requesting radiological investigations, as required legally by UK government legislation 'Ionising Radiation (Medical Exposure) Regulations 2000' (IRMER 2000), following the implementation of European Working Time Directive.
Design:
Cross sectional survey.
Participants:
All doctors requesting radiological requests every Monday, following the weekend on-call, over an 8-week period. There were no exclusion criteria.
Main Outcome Measures:
Baseline data analysis, including grade and specialty of requesting doctor, types of modality requested, knowledge of their patient, addressograph signature confirming identity and appropriateness of investigation.
Results:
164 requests were received, the majority (61%) were made by Foundation Programme 1 (FP1) doctors and general medical specialties accounted for the highest proportion of requests (45%). Ultrasound scanning was the most frequently requested investigation (47%), closely followed by computed tomography (CT) scans (42%). Almost a third (30%) of requests were made by doctors who had not seen the patient to be investigated, predominantly by FP1 doctors (p=0.003) and more frequently by general medical specialties (p=0.001). Signatures were absent on 20% of the addressographs and overall, 10% of requests were deemed inappropriate.
Conclusions:
In almost a third of radiological requests, doctors have not seen patients to be investigated, most likely as a result of shift working patterns. This does not fulfil the IRMER 2000 criteria and potentially exposes patients to unnecessary and inappropriate radiation.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
