Comparative StudyOptimising the dosimetric quality and efficiency of post-prostatectomy radiotherapy: a planning study comparing the performance of volumetric-modulated arc therapy (VMAT) with an optimised seven-field intensity-modulated radiotherapy (IMRT) technique.
The purpose of this study was to compare and evaluate radiotherapy treatment plans using volumetric modulated arc therapy (VMAT) and intensity modulated radiotherapy (IMRT) for post-prostatectomy radiotherapy. ⋯ VMAT can achieve post-prostatectomy radiotherapy plans of comparable quality to IMRT with the potential to reduce dose to OAR and improve the efficiency of treatment delivery.

Case ReportsUncommon pulmonary metastasis presenting as pulmonary infarction with tumour emboli in two cases.
We report two cases of pathologically proven pulmonary metastases presenting as pulmonary infarction with tumour emboli. In two cases, high-resolution CT showed multiple small subpleural consolidations in both lungs. The patients had breast cancer and uterine cervix cancer, respectively. Although various pulmonary diseases show subpleural consolidations on CT, pulmonary metastases by tumour emboli should be primarily considered in differential diagnosis especially when the patient has known malignancy.
