RESUMEN
Objective To investigate the application of CT lamellar scanning and HRCT technique in thoracic dis- eases. Methods Sixty cases were lamellar scanned (lamella thick 2mm～5mm) with double helix CT machine, and twenty cases were scanned by HRCT technique. Results Thirty cases pulmonary carcinoma,sixteen pulmonary tuberculosis (TB) and tuberculoma, four metastatic tumor (MT),eight thoracic inflammation, five interstitial pneumonia , five inflammatory pseudotumor, eight bronchiectasis and four primary mediastinal tumor were proved after CT scanning. Conclusion Minute focus can be found by thoracic lamellar scanning. The specific character of focus can be showed in HRCT technique. The resolution of focus can be raised.
RESUMEN
The quality of CT diagnosis depends on the quality of scanning which is related to accurate scanning design and quality control on work process. The quality control of work procedure includes training of patients' breathing, reasonable application of window technique, accurate mark, size and CT value,washing and print of films. In addition, the coordination of clinical doctors, imaging doctors and CT technicians is very important. According to CT standards, precise CT scanning by CT design request, can provide a high quality CT images that reflect pathologic state of human body, thereby to raise the quality of CT diagnosis.
