Objective:
Increasing numbers of avalanche victims with polytrauma have highlighted their need for radiological injury characterisation, which this study examines.
Methods:
People in Tirol injured by avalanche during 1994-2005 and admitted to the Innsbruck Medical University Hospital were included. Data for this retrospective study were obtained from the Austrian avalanche register and local electronic patient files archive.
Results:
During the observation period 94 avalanche victims in Tirol were admitted to our hospital, and a mean of 1.5 radiological methods were used per person at presentation. A mean of three diagnoses per victim were recorded, of which one was eligible for radiological examination only. Most victims (56%) were diagnosed with hypothermia, followed by unspecific contusion (54%), injuries of ligaments, tendons or muscles (26%) and fracture (23%); 21 victims died in hospital.
Conclusions:
Emergency radiological examination can discover injuries otherwise not immediately apparent. However, initial use of radiological assessments such as computed tomography for people admitted under cardiopulmonary resuscitation does not always ensure an optimal outcome.

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...

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...

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...
