Objective:To explore the diagnosis and differential diagnosis value of MSCT in the subtypes of renal cell carcinoma and preferentially choose meaningful CT signs to further define the differential diagnosis standard.Materials and Methods:The Clinical Parameters and CT datas of the136patients with kidney cancer were retrospectively reviewed. There were112cases with clear cell RCC,15cases with papillary RCC and9cases [...]
Objective By measurement and analysis the lung cancer patients different single-energthe tumor CT value and the tumor iodine content changes,to explore the value of CT spectralimaging for biological therapy of lung cancer.Methods 40 cases biological therapy of lung cancer patients（20 cases were central lungcancer , 20 cases were peripheral lung cancer）were underwent spectral CT normal [...]
【Background】Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease and characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lung to noxious particles or gases. COPD is one of the leading causes of morbidity and mortality and one [...]
Objective To investigate the valuation of MSCT in the diagnosis of pulmonary arterial hypertension(PAH) in COPD.Methods The diameters and areas of the pulmonary artery were measured in81cases with COPD and100cases normal adult,and the ratio of the diameters and areas of main pulmonary artery (MPA) to ascending aorta(AA),descending aorta(DA),trachea, thoracic vertebra(ThV) were also caculated.To analyze the [...]
Objectives: To evaluate the clinical value of256-row Spiral CT andUltrasound in the diagnosis of aortic intramural hematoma(IMH).Methods：Between January2009and January201127patients (male19,female8) who were examined by256-row Spiral CT and Ultrasound werediagnosed with IMH. Scanner is Philips Brilliance256-row CT. Scan range isfrom thoracic entrance to bilateral common iliac artery.Double tube highpressure syringe inject a contrast agent.①Non ionic contrast [...]
Objective:Preparation of small pulmonary nodules model, To analysis the accuracy of Lung VCAR software for small pulmonary nodules volume by MSCT with different doses. Selecting the volume measurement software and establishing reasonable reconstruction parameters, In order to perform a wide range of lung cancer screening with low dose spiral CT.Methods:Seven porcine lungs were inflated and [...]
Objective To study the variation types of the aortic arch branches in Chinese using multi-slice spiral computed tomography angiography(MSCTA).Materials and Methods MSCTA data from 834 patients who had undergone cervical and head examination were retrospectively analyzed. Two experienced radiologists read the images together. The axial images were used as basic images, MIP and VR techniques [...]
The Comparative Study of Ultrasound and CT in Diagnosis of Hepatic Inflammatory Myofbroblastic Tumor
Objective To evaluate the ultrasonography and CT in the diagnosis of hepaticinflammatory myofibroblastic tumor(HIMT) and compare the diagnosis value of twomethods.Methods45poorly blood supplying liver tumor cases confirmed by surgery include15cases of HIMT,11cases of single liver tumor,9cases of intrahepatic peripheralcholangiocarcinoma,5cases of poorly blood supplying liver cancer,5cases ofhepatapostema analyzed their dynamic contrast-enhanced spiral CT and ultrasonographyimages retrospectively. [...]
Objective To evaluate the features of CT and MRI in the diagnosis of commoncystic tumors of the pancreas.Materials and Methods Analyzed retrospectively59cases of common cystictumors of the pancreas on MSCT and MRI material, male25cases, female34cases, age34to74years old, including serous cystic neoplasm (SCN)18cases, mucous sex cysticneoplasm (MCN)19cases, intraductal papillary mucinous neoplasm(IPMN)22cases.Recorded the size, the site, the [...]
