Conclusions L-SURmax showed the most powerful predictive performance than the other PET parameters in predicting occult lymph node metastasis. The combination of three independent risk factors (carcinoembryonic antigen, cytokeratin 19 fragment, and L-SURmax) can effectively predict occult lymph node metastasis in clinical N0 non–small cell lung cancer patients.

AbstractLymph node assessment is an essential component of the treatment of lung cancer. Identification of the correct “N” stage is important for staging which in turn determines treatment. Assessment of lymph nodes may be accomplished using imaging with CT scan and PET–CT, invasive techniques such as mediastinoscopy, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) or endoscopic ultrasoun d fine needle aspiration (EUS-FNA). Ultimately, regardless of any pre-resection assessment, lymph nodes must be assessed at the time of resection. The question to be addressed in this report is the ...

Abstract PURPOSE: We compare the effect of tube current modulation (TCM) and fixed tube current (FTC) on size-specific dose estimates (SSDE) and image quality in lung cancer screening with low-dose CT (LDCT) for patients of all sizes. METHODS: Initially, 107 lung screening examinations were performed using FTC, which satisfied the Centers for Medicare &Medicaid Services' volumetric CT dose index (CTDIvol ) limit of 3.0 mGy for standard-sized patients. Following protocol modification, 287 examinations were performed using TCM. Patient size and examination parameters were collected and water-equivalent...

AbstractAir leakage is a common complication after pulmonary resection, which is usually caused by direct lung damage during surgery. Herein, we describe a case in which a pulmonary cyst developed rapidly in the right lower lobe and ruptured 10  days after right upper lobectomy. A 49‐year‐old man, who was a heavy smoker, underwent thoracoscopic right upper lobectomy for primary lung cancer. No air leakage was observed postoperatively, and the chest drain tube was removed on postoperative day 1. Although his postoperative course was u neventful for more than a week, extensive subcutaneous emphysema developed unex...

In Reply We thank Bernheim for his thoughtful comments on our recently published Original Investigation. The American College of Radiology (ACR) and Centers for Medicare&Medicaid Services recommend a maximum volumetric computed tomography dose index (CTDIvol) of 3 mGy for lung cancer screening. As a measure of the average dose per slice, CTDIvol will reflect many of the scanning decisions made by the radiologists and technologists, and reliably measure average doses that patients will receive.

To the Editor In response to the recently published Original Investigation by Demb and colleagues regarding computed tomography (CT) radiation doses for lung cancer screening scans, I have concerns about the statements made about effective doses. The National Lung Screening Trial reported an average radiation effective dose of 1.5 mSv for CT scans performed in the trial. Demb and colleagues state that “[the American College of Radiology] recommends that [lung cancer screening] scans have…an effective dose of 1 mSv or lower.”(p1651) This dose is 33% less than the dose in the National Lung Screening Trial,...

This study aimed to investigate the clinical features and the onset risk factors of DILI by ALK‐TKIs in clinical practice.MethodsThe clinical features of 56 consecutive patients who received crizotinib, alectinib, and/or ceritinib at our hospital from 2012 to 2018 were retrospectively examined. Among these, patients diagnosed with DILI due to ALK ‐TKIs were evaluated in terms of clinical features and parameters. Each clinical parameter before the administration of ALK‐TKIs was compared between the DILI onset group and the non‐onset group.ResultsA total of seven cases were diagnosed with DILI due to ALK ‐TKIs; no ...

When a scanner is installed and begins to be used operationally, its actual performance may deviate somewhat from the predictions made at the design stage. Thus it is recommended that routine quality assurance (QA) measurements be used to provide an operational understanding of scanning properties. While QA data are primarily used to evaluate sensitivity and bias patterns, there is a possibility to also make use of such data sets for a more refined understanding of the 3-D scanning properties. Building on some recent work on analysis of the distributional characteristics of iteratively reconstructed PET data, we construct ...

Abstract While many pre-defined computed tomographic (CT) measures have been utilized to characterize chronic obstructive pulmonary disease (COPD), it is still challenging to represent pathological alternations of multiple dimensions and highly spatial heterogeneity. Deep CNN transferred multiple instance learning (DCT-MIL) is proposed to identify COPD via CT images. After the lung is divided into 8 sections along the axial direction, one random axial CT image is taken out from each section as one instance. With one instance as the input, the activations of neural layers of AlexNet trained by natural images are ex...
