Medical significance of MDCT MPR reconstruction function for the lesion in central airway

Central Plains Medical Journal (2011)

Li-shan Kuang Yuqing Shan Yongchun Qin Hong Yan

Objective To investigate the diagnostic value and directing significance in treatment of MSCT, MPR reconstruct for the lesion in central airway. Methods MSCT was performed on 9 patients with lesion in central airway. The images were reconstructed with MPR on the workstation, then the axial images and the reconstruction images were compared and analyzed. Results MPR reconstruct can reveal explicity the structure of central airway, postion and size of lesion, degree of lumen narrow, truncation,proliferation of trachea and change of exterior central airway. Afert the analysis for 6 cases of tumor in the central airway and 3 cases of Foreign body in trachea. Conclusions Spiral CT, MPR can evaluate the relation of anatomy and pathology for central airway, it is a useful techniquer for diagnosis and differentialdiagnosis for the lesion in the central airway, moreover it can guide the treatment.

Judgment for cause of radiogenic neoplasms for a thyroid cancer

Journal of Public Health and Emergency (2017)

Yongchun Qin Jin Wang Yimei Zhang Xiaomin Zhu Ningle Yu

Background: Radiogenic neoplasms due to occupational exposure can be identified as occupational radiogenic neoplasms. We investigate the etiology of cancer in a patient with thyroid carcinoma. Methods: Organ dose was estimated based on the individual monitoring results, or according to GB/T 16149-2012 “Specification of dose estimation for chronic radiation sickness from external exposure” when no individual dose was provided; PC (probability of causation) was calculated according to GBZ97-2009 “Judgment criteria for cause of radiogenic neoplasms”. Results: The estimated cumulative dose was 20.4 cGy, organ dose of thyroid was 38.1 cGy, PC value from occupational exposure was about 37.8%, with its upper limit of the 95% confidence level was 82.6%. Conclusions: The case can be judged as radiogenic neoplasm as the upper limit of the 95% confidence PC value is more than 50%. More attention should be paid to the examination of thyroid palpation and the thyroid B ultrasound for radiation workers, especially for those high-risk individuals engaged in radiation work in their early years.
