To investigate the correlation between iodine concentration of dual-energy CT (DECT) and histopathology surgically resected primary lung cancers.We reviewed medical records, post-operative pathological records pre-operative DECT images patients who underwent surgical resection for cancer. After injection iodinated contrast media, arterial delayed phases were scanned using 140- 80-kV tube voltages. Three-dimensional (iodine volume) tumours was calculated nodule application software.A total 60...
We compared the efficacies of (18)F-FDG PET and (99m)Tc-bone scintigraphy for detection bone metastases in patients with differentiated thyroid carcinoma (DTC).We examined 47 (32 women, 15 men; mean age +/- SD, 57.0 10.7 y) DTC who had undergone total thyroidectomy were hospitalized to be given (131)I therapy. All underwent both whole-body scintigraphy. The skeletal system was classified into 11 anatomic segments assessed presence metastases. Bone verified either when positive findings...
Objective Endobronchial ultrasonography with a guide sheath (EBUS-GS) and virtual bronchoscopic navigation (VBN) improves the diagnostic yield in patients peripheral pulmonary lesions (PPLs). Most previous reports on EBUS-GS-guided transbronchial biopsy (TBB) have included benign malignant diseases. We aimed to determine factors that predicted successful diagnosis by TBB small lung cancer, focus high-resolution computed tomography (HRCT) findings before bronchoscopy. Methods retrospectively...
Purpose To investigate the relationship between postoperative prognosis of patients with part-solid non-small cell lung cancer and solid component size acquired by using three-dimensional (3D) volumetry software on multidetector computed tomographic (CT) images. Materials Methods A retrospective study preoperative CT data 0.5-mm section thickness, clinical records, pathologic reports 96 primary subsolid (47 men 49 women; mean age ± standard deviation, 66 years 8) were reviewed. Two...
Purpose: Visualization of endolymphatic hydrops by 3-dimensional fluid-attenuated inversion recovery-FLAIR using conventional turbo-spin-echo (3D-FLAIR-CONV) after intratympanic injection Gd-DTPA has been reported in patients with Ménière's disease. Compared to 3D-FLAIR-CONV used previous studies, the addition a variable flip-angle technique (3D-FLAIR-VFL) enables very long echo trains and, therefore, shorter scan times. We evaluated whether 3D-FLAIR-VFL could replace detecting...
Differentiation between metastasis-free pancreatic cancer and mass-forming pancreatitis is important to avoid unnecessary operative procedures. This study was aimed at evaluating the efficacy of PET/CT with F-FDG (FDG PET/CT) for differential diagnosis them.FDG-PET/CT performed in 47 patients masses without any detectable metastases, 33 which cases were finally diagnosed as other 14 pancreatitis, corresponding imaging data evaluated retrospectively. The maximal SUV (SUVmax) within determined...
Recent studies suggest that coexistence of chronic obstructive pulmonary disease (COPD) might be independently related to a worse prognosis for lung cancer. However, because data on the substantial prevalence COPD and its severity in Asian cancer patients remain limited, clinical impact among population has not been fully evaluated. Furthermore, with often have comorbidities. Thus, whether decision-making process therapeutic management affected by remains elusive.Clinical were evaluated 270...
We compared the efficacies of ¹⁸F-fluoride positron emission tomography (¹⁸F-fluoride PET)/CT, ¹⁸F-fludeoxyglucose PET (¹⁸F-FDG and ⁹⁹mTc bone scintigraphy [planar single photon CT (SPECT)] for detection metastases in patients with differentiated thyroid carcinoma (DTC).We examined 11 (8 females 3 males; mean age 6 standard deviation, 61.968.7 years) DTC who had been suspected having after total thyroidectomy were hospitalized to be given ¹³¹I therapy. Bone verified either when positive...
We propose a novel mediastinal lymph node detection and segmentation method from chest CT volumes based on fully convolutional networks (FCNs). Most methods are filters for blob-like structures, which not specific nodes. The 3D U-Net is recent example of the state-of-the-art FCNs. can be trained to learn appearances nodes in order output likelihood maps input volumes. However, it prone oversegmentation each due strong data imbalance between remaining part To moderate balance sizes target...
Abstract Objectives Chest wall infiltration in primary lung cancer affects the surgical and therapeutic strategies. This study evaluates efficacy of chest vessel involvement subpleural (CWVI) on ultra-high-resolution CT (UHR-CT) for detecting invasion. Materials methods A retrospective analysis cases with confirmed pleural invasion was conducted from November 2019 to April 2022 . Seventy-seven patients (mean ± standard deviation age 70 8 years, 64 males) who underwent preoperative...
Peripheral helper T (Tph) cells, together with plasma are the major pathogenic lymphocytes in synovium rheumatoid arthritis (RA). However, whether these cells involved RA-associated lung and/or airway disease is unknown. Tph sputum were analyzed by flow cytometry and compared those synovial fluid tissue. Forty RA subjects for whom induced could be collected along several clinical parameters; severity was assessed using Disease Activity Score 28 joints (DAS28). Lung chest computed tomography...
