Objective:
To assess the clinical value of multi-slice CT in one-stop examination of thoracic and abdominal injuries in earthquake victims.
Methods:
DR and multi-slice CT examination were performed in 162 earthquake victims with thoracic and abdominal injuries. Optimal processes and preferred modalities were identified through comparisons of examination time, radiation dose and diagnostic value between the two methods.
Results:
The multi-slice CT took (5 +/- 2) min, shorter than that of DR (10 +/- 3) min (P < 0.001). The radiation dose of multi-slice CT (6.4 +/- 1.7) mSv was higher than that of DR (2.4 +/- 1.3) mSv (P < 0.001). Both methods were able to detect bone fracture (clavicle, rib, sternum, thoracic spine, lumbar and pelvic). However, soft-tissue organ trauma, such as liver, pancreas and spleen could not be detected by DR. Multi-slice CT had significantly higher sensitivity (98%) and specificity (97%) in detecting thoracic and abdominal injuries than DR (74%, 67%).
Conclusion:
Multi-slice CT one-stop examination is a preferred method for detecting combined injuries in emergency events, as it can save examination time and obtain reliable diagnostic information.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...
