This paper presents a novel semi-automatic method for lung segmentation in thoracic CT datasets. The fully three-dimensional algorithm is based on a level set representation of an active surface and integrates texture features to improve its robustness. The method’s performance is enhanced by the ...
Objective:To study the changes of CT dynamic contrast-enhanced scan parameters in patients with lung cancer before and after radiofrequency ablation (RFA) and their correlation with serum tumor markers.Methods:A total of 60 patients who were diagnosed with lung adenocarcinoma in the Second Hospital ...
CTSmall cell lung cancerSurvivalTexture analysisThe purpose of this study was to investigate the relationship between x-ray computed tomography (CT) texture features of small cell lung cancer (SCLC) and the survival of the patients. Eighty-eight......
Figure 4: Noncontrast axial CT scans at T0 in a 63-year-old woman with lymphadenopathy show (A) 13-mm ground-glass nodule (arrow) in the right lower lobe and (B) 15-mm subcarinal lymphadenopathy (arrow). (C, ...
In our experiments, we focused on the complex task of CT lung registration, as the registration results can be evaluated more accurately than only with an overlap of a larger structure. However, our method could also be trained for a different task or on a different modality. Except for key...
Whole-body PET scans had been acquired using three different models of PET/CT scanners (Siemens Biograph 16, Philips Gemini GXL, Philips Gemini TF16) with full-dose contrast-enhanced or low-dose non-contrast-enhanced CT for attenuation correction and anatomical co-registration. Image acquisition ...
Methods: Twenty-six patients of non-calcified and with fatty density in lung hamartoma proved by surgery were studied. Nineteen patients underwent conventional CT, seven patients underwent dynamic contrast enhanced CT. Result: All lung hamartomas were round or oval and had clear margins. Eight ...
【摘要】目的探讨肺结核空洞和癌性空洞的CT影像学表现及鉴别诊断价值。方法收集14例肺结核空洞和36例肺癌空洞的临床和CT资料, 对其CT征象进行回顾性研究。结果结核空洞空洞壁较薄,且洞壁钙化、周围卫星灶多见;肺癌空洞空洞壁较厚,以壁结节、偏心空洞、 深分叶、粗短毛刺、胸膜凹陷为多见。结论利用CT检查,可以详细...
Objective To investigate the application value of contrast-enhanced multislice spiral CT(MSCT) in judging the feasibility of excision of lung cancer. Methods The contrast-enhanced MSCT images of 68 patients with non-small cell lung cancer(NSCLC) diagnosed by operation or biopsy in our hospital from...
