PDFAbstract
Objective To investigate the clinical value and feasibility of low-dose 70kv.50mAs MSCT perfusion imaging in the evaluation of patients with lung cancer. Methods Retrospectively studied 45 cases(squamous carcinoma 15 cases, adenocarcinoma 23cases, small cell carcinoma 7cases) lung cancer confirmed by operation and pathology, these patients were undergone low-dose(70kv.50mAs)MDCT perfusion scanning before operation. The original images were processed by perfusion software. The value of time to peak(TTP), blood flow (BF), blood volume (BV) and permeability (PMB) were calculated, and gained perfusion image. Results The TTP (s) of squamous carcinoma, adenocarcinoma, small cell carcinoma were 15.62、17.91、16.89. The BF (ml/100ml/ min) of squamous carcinoma, adenocarcinoma, small cell carcinoma were 91.72, 77.27, 90.60;The BV (ml/100ml) of squamous carcinoma, adenocarcinoma, small cell carcinoma were 8.06, 8.94, 11.94. The PMB(ml/100ml/min)of squamous carcinoma, adenocarcinoma, small cell carcinoma were 13.79, 15.17, 13.95. Conclusion The lowdose(70kv.50mAs)MSCT perfusion scanning could gained good perfusion image and calculated tumor's value of TTP, BF, BV, PMB, it was a effective evaluation analysis for tumor's blood supply and perfusion.
