但是,仔细推敲、也存在诸多疑问:患者半月前行左肾结石钬激光取石,左肾未见肿瘤,活检「炎性肉芽肿」;肿瘤标志物未见明显异常、且t-spot阳性、肺部多发小结节影,再次仔细对比患者既往2014年6月份术前与术后7月底的胸片(下方图3),7月...
但是,仔细推敲、也存在诸多疑问:患者半月前行左肾结石钬激光取石,左肾未见肿瘤,活检「炎性肉芽肿」;肿瘤标志物未见明显异常、且t-spot阳性、肺部多发小结节影,再次仔细对比患者既往2014年6月份术前与术后7月底的胸片(下方图3),7月份的胸片可见右下肺明显小结节; 再结合住院期间的胸腹部CT检查,可见双肺、主要是...
PET Marks the Spot: Incidental Finding of a Tubulovillous Adenoma on Positron Emission Tomography of a Lung Nodule: 1085Furman, DavidWong, RoyOfficial journal of the American College of Gastroenterology | ACG
is a next-generation small-molecule inhibitor of the orphan receptor tyrosine kinase c-ros oncogene 1 (ROS1), which has a kinase domain that is physiologically related to anaplastic lymphoma kinase (ALK), and is undergoing Phase I/II clinical trial investigations for non-small cell lung cancers...
Another such factor, interstitial pneumonitis (IP) on pretreatment computed tomography (CT) scans, has been shown to predict an increased risk of symptomatic RP [18–20]. Makimoto et al. [18] found that in patients with primary lung cancer, pre-existing lung disease evidenced by pretreatment ...
after the administration to an inferior right part of the lung (Fig.4c) remaining in this region for the rest of the scan (Fig.4d). The anterior–posterior movement of the particle once within the lungs was confined to approximately ±2 mm, suggesting that the motion followed the ...
SAM YEH, MD:Let’s say you do find a focal spot and you radiate the focal spot; what if the patient is totally asymptomatic? What’s the role of that? DEKKER:We make the same assumption that we do with melanoma, with renal cell, isolated lung, isolated colorectal. Isolated disease cou...
Small Cell Lung Carcinoma (SCLC): FDG-PET scans are considered medically necessary for staging of persons with SCLC that has been determined to be of limited-stage after standard staging evaluation (including CT of the chest and upper abdomen, bone scan, and brain imaging). ...
For example, preparing a training dataset for position estimation requires a precise and reproducible setup of a single pencil beam and several measurements at any possible spot within the field-of-view. A number of recent studies came up with novel ideas to perform these tasks for monolithic ...
Increased myocardial FDG uptake has been reported following radiation therapy for esophageal cancer [88,89,90] and lung cancer [91]. In this setting, FDG uptake has the feature of unusual sharp borders that correlate with the area of heart involved in the radiation therapy planning field, ...
