Differential radiologic characteristics of renal tumours on multiphasic computed tomography.

Introduction: This study analysed the tumour attenuation characteristics of different subtypes of renal cell carcinomas (RCCs), including clear cell RCC (ccRCC), papillary RCC (pRCC), mixed RCC, chromophobe RCC (chRCC) and oncocytoma.

Methods: We randomly selected 100 RCC cases that underwent nephrectomy between 2004 and 2012 from a collaborative database. Of these cases, 36 were excluded due to the absence of available imaging.

Breast cancer detection of large size to DCIS by hypoxia and angiogenesis using NIRS.

This investigation aimed to test all tumor-bearing patients who undergo biopsy to see if angiogenesis and hypoxia can detect cancer. We used continuous-wave near-infrared spectroscopy (NIRS) to measure blood hemoglobin concentration to obtain blood volume or total hemoglobin [Hbtot] and oxygen saturation for the angiogenesis and hypoxic biomarkers. The contralateral breast was used as a reference to derive the difference from breast tumor as a difference in total hemoglobin Δ[HBtot] and a difference in deoxygenation Δ([Hb]-[HbO2]).

Local experience of endorectal magnetic resonance imaging of prostate with correlation to radical prostatectomy specimens.

Introduction: We evaluated the accuracy of endorectal magnetic resonance imaging (MRI) in the staging of prostate cancer.

Materials And Methods: We retrospectively reviewed 32 patients who underwent endorectal MR prostate prior to radical prostatectomy. The tumour stage based on MR imaging was compared with the pathologic stage.
