Objective:
To evaluate the value of clinical application of multiplanar reconstruction (MPR) and volume rendering (VR) with 64-slice spiral CT in the complex midfacial fracture.
Method:
Forty-six patients with the complex midfacial fracture were examined with 64-slice spiral CT, then MPR and VR were performed in work station.
Result:
Of 46 patients, there are 366 fractures. MPR imaging clearly showed all (the rate were 100%). VR imaging could show all zygomatic fracture and mandibular fracture (the rate were 100%), but the showed rate were 94.3% in maxillary fracture, 93.2%. in orbital fractures, 13.0% in ethmoid fractures, 55.6% in sphenoid bone fracture,the mean rate were 86.3%. VR imaging could show the fracture location, range, fragment displacement from different direction by rotating picture and demonstrate the course of fracture line and deformities caused by fracture.
Conclusion:
MPR imaging combination with VR imaging has important clinical value in diagnosing the complex midfacial fracture. 64 slice CT may improve displaying tiny and deep fracture.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

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...
01:10Computed 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...
