An 85-year-old man underwent abdominal aortic aneurysm (AAA) repair with a synthetic graft at age 48. Sac enlargement, likely due to an endoleak, was observed during follow-up, and covered stents were placed in the limbs 80. Despite this, sac continued enlarge, leading referral our institution. Imaging revealed endoleak from uncovered section. EXCLUDER® stent (W. L. Gore & Associates, Inc., Flagstaff, AZ) cover entirely, resolving endoleak. The patient discharged on postoperative day 5. This...
Aim In computed tomography colonography angiography (CTC-A), used for preoperative screening of right-sided colon cancer, the timing venous phase imaging is conventionally determined by a fixed-delay time; however, contrast effect may be insufficient because individual differences in blood flow status. Therefore, we developed double-bolus tracking (DBT) method to solve this issue. Method We compared and image quality portal systems between two methods conventional DBT which utilizes low-dose...
To report the initial outcomes of physician-modified inner branched endovascular repair (PMiBEVAR) for pararenal aneurysms (PRAs), thoracoabdominal aortic (TAAAs), and arch in high-surgical-risk patients.A total 10 patients (6 men; median age, 83.0 years) treated using PMiBEVAR were enrolled this retrospective, single-center study. All at high surgical risk because severe comorbidities (American Society Anesthesiologists physical status score≥3 or emergency repair). End points defined as...
Abstract Aims Elevated plasma branched‐chain amino acids (BCAAs) are tightly linked to incident diabetes and its complications, while lower BCAAs associated with adverse outcomes in the elderly heart failure (HF) patients. The interplay between body compositions BCAAs, especially under influence of co‐morbid HF patients, is not well understood. Here, we examined impact on prognostic value BCAA association Methods results We retrospectively 301 patients (70 ± 15 years old; 59% male), among...
Since the response to lung recruitment varies greatly among patients receiving mechanical ventilation, recruitability should be assessed before maneuvers. The pressure-volume curve (PV curve) and recruitment-to-inflation ratio (R/I ratio) can used bedside for evaluating individualing positive end-expiratory pressure (PEEP). Lung tissue on computed tomography has been correlated with normalized maximal distance (NMD) of quasi-static PV curve. NMD is between inspiratory expiratory limb volume....
A 74-year-old man, who was diagnosed with primary lung adenocarcinoma, underwent video-assisted thoracoscopic left segment 6 segmentectomy.Preoperative three-dimensional contrast-enhanced computed tomographies (Fig. 1) guided the surgeons in avoiding injury to anomalous A6c, and distinguishing latter from lower basal dorsal pulmonary artery during VATS segmentectomy (VATS, videoassisted surgery; Fig. 2).
Abstract A 69-year-old woman with a pulmonary nodule in anterior basal segment of the right lower lobe (RS8) was referred to our department. The diameter tumor 12 mm, and it had increased over few months. First, video-assisted thoracoscopic lung surgery (VATS) biopsy carried out. Frozen section examination this confirmed diagnosis bronchioloalveolar carcinoma (BAC). Segmentectomy RS8 mediastinal node dissection (ND2a-1) performed. intersegmental plane identified using veins as landmarks...
Background Reliable size measurement of lymph node (LN) metastases is important for the evaluation cancer treatment. However, image analyses without proper settings may result in inappropriate diagnoses and staging. Purpose To investigate whether reconstruction slice thickness computed tomography (CT) affects measurements LN reproducibility. Material Methods We analyzed 48 patients with histological sigmoid colon rectal who underwent contrast-enhanced CT colonography as part a surgical...
Objective To assess the limitations of single-energy metal artifact reduction algorithm in oral cavity and evaluate availability a solution by setting patient lateral position (LP) with use gantry tilt (GT). Methods We analyzed 88 patients dental metals retrospectively study 1, 74 prospectively 2. Patients were classified: I 1 region, II 2 regions, III 3 regions. underwent neck computed tomography examinations supine (SP) positions, an LP GT SP, All images reconstructed this algorithm. Image...
Background: Evaluation of sarcopenia requires quantifying appendicular skeletal muscle mass and functional capacity, but resource constraints often limit feasibility. Alterations in quality, especially intramuscular lipid infiltration (i.e., myosteatosis), systemic metabolic derangements are associated with disability. Hypothesis: Opportunistic CT imaging plasma amino acid profiling could identify low physical function patients heart failure (HF). Methods: We retrospectively examined 220 HF...
Motivation: The fatal accidents in the MRI room are caused by bringing of ferromagnetic objects. It is necessary to identify trends incidents. Goal(s): Our goal was investigate relationship between frequency objects and years experience. Approach: We compiled incident reports for past 10 years, extracted related Results: There were 26 brought introduced, half from technologists with less than one year Impact: In order prevent adsorption objects, it important understand causes such incidents...
Abstract The frequency of bronchial branching abnormalities is about 0.6%, which 75% are related to the right upper lobe. left B1 + 2 transition bronchus even rarer, but a few cases have been reported. A 43-year-old man, who presented with an abnormal pulmonary nodule suspected be lung cancer in S4 segment, underwent video-assisted thoracoscopic segmentectomy S3 plus lingular segment. Preoperative three-dimensional contrast-enhanced computed tomography (CT) revealed displaced arising from...
Abstract Normally aerated lung tissue on computed tomography (CT) is correlated with static respiratory system compliance (C rs ) at zero end-expiratory pressure. In clinical practice, however, patients acute failure are often managed using elevated PEEP levels. No study has validated the relationship between volume and C applied positive pressure (PEEP). Therefore, this aimed to demonstrate CT during application of for management distress syndrome due COVID-19. Additionally, as a secondary...
We report a case of 71-year-old female with primary cardiac tumor. The patient had undergone surgery for uterine cancer 10 years ago and presented to nearby clinic complaining dyspnea on exertion. Chest X-ray revealed enlargement, prompting further investigations, which massive tumor protruding into the left atrium extending toward outer wall ventricle. was referred department myocardial biopsy. biopsy confirmed diagnosis vascular Due tumor's large size difficulty in achieving complete...
Background: The 320-row area detector computed tomography (ADCT) for the evaluation of left ventricular (LV) systolic function has been reported, but reporting ADCT LV diastolic (LVDF) cannot be found. purpose this study was to examine usefulness in assessment and compared ultrasound echocardiography (Echo) as standard reference. Materials methods: We evaluated 60 consecutive patients (mean age 62.4±13.2 years, male/female 36/24) who underwent (retrospective electrocardiogram triggered)...
The optimal imaging conditions for 3D brain surface by magnetic resonance (MRI) and multi-slice CT were investigated. Visualization of the sulci, gyri, veins on brain's was also compared between images acquired using conventional single-slice MRI. Various parameters, including slice thickness, dose, matrix size, evaluated our original phantom longitudinal direction evaluation as well obtained from healthy volunteers. Subjects clinical study patients with arteriovenous malformations tumors...
