The use of programs of post-processing of MDCT (Multi Detectors Computed Tomography) images as an aid to the radiologist foridentification of the angle of shot of bullets has been previously described, however, to the best of our knowledge, the uses of programs in the identification of both terminal and external ballistic of projectile have never been reported. The objective of this work is to use a software commonly applied to localize the tumor for treatment planning in the field of radiation therapy, to define the...

We evaluated two cases of gunshot injuries. A 16-Row MDCT scans (GE lightspeed plus 16) total body was performed for the first patient, that received 120 ml of contrast medium (Iomeprol, 350 mgI/ml), with an injection rate of 4 ml/sec. The automatic bolus triggering software program was applied to a circular region of interest positioned at the level of the descending aorta and a threshold for triggering preset at 150 HU. The second patient undergone a CT scans of the head: he received 40mL of...

CASE ONE: STUDY OF EXTERNAL BALLISTIC A patient was taken to the emergency room with gunshot wounds, he appeared ill and sweaty, with a bullet entrance hole in the left sacral wing, no abdominal pain, no hematuria. The CT scan identified high density object in the subcutaneous inguinal region close to the right femoral artery. The entrance hole was located in the left gluteal region, the bullet penetrated at the posterior edge of the iliac wing and crossed the sacral sincrondrosis passing through the posterior...

The decision to use tools of radiotherapy planning CT image processing in order to obtain three-dimensional images, came from a study by Oliver et al in 1995 [1], where the radiation oncology software was used to create a three-dimensional reconstruction of the path of a bullet in the skull. This study was repeated at other times, as an implement to forensic diagnostics. In particular, Marchetti et al [2] demonstrated the usefulness of tomographic reconstructions using the software "Plato" to identify the angle of shot, starting...
