Right adrenal vein identification using unenhanced magnetic resonance imaging.

Purpose: Unenhanced magnetic resonance imaging (MRI) is known to be useful in characterizing adrenal adenomas through the implementation of in-phase (IPI) and opposed-phase imaging (OPI) based on chemical shift artifacts. However, whether unenhanced MRI can contribute to the identification of right adrenal vein (RAV) remains unclear. The aim of this study was to evaluate the feasibility of unenhanced MRI for the identification of RAV.

Analysis of "visible in retrospect" to monitor false-negative findings in radiological reports.

Purpose: False-negative findings in radiological reports can lead to serious adverse patient outcomes. We determined the frequency and tendency of false-negative findings in radiological reports by searching for words related to "visible in retrospect".

Methods: In the period of 34 months, we extracted radiological reports containing words related to "visible in retrospect".

Different hemodynamics of basal ganglia between moyamoya and non-moyamoya diseases using intravoxel incoherent motion imaging and single-photon emission computed tomography.

Background: Moyamoya disease (MMD) and non-MMD have different pathogenesis, clinical presentation, and treatment policy.

Purpose: To identify differences in hemodynamics between MMD and non-MMD using intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT).

Material And Methods: Patients who had undergone Tc-ECD or I-IMP SPECT, and IVIM imaging were retrospectively studied.

Right entorhinal cortical thickness is associated with Mini-Mental State Examination scores from multi-country datasets using MRI.

Purpose: To discover common biomarkers correlating with the Mini-Mental State Examination (MMSE) scores from multi-country MRI datasets.

Methods: The first dataset comprised 112 subjects (49 men, 63 women; range, 46-94 years) at the National Hospital Organization Kyushu Medical Center. A second dataset comprised 300 subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database (177 men, 123 women; range, 57-91 years).

Identification of predictors for mini-mental state examination and revised Hasegawa's Dementia Scale scores using MR-based brain morphometry.

Purpose: The early detection of cognitive function decline is crucial to help manage or slow the progression of symptoms. The Mini-Mental State Examination (MMSE) and revised Hasegawa's Dementia Scale (HDS-R) are widely used in screening for cognitive impairment. The purpose of this study was to explore common predictors of the two different cognitive testing systems using MR-based brain morphometry.

Supraduodenal and Right Gastric Arteries Originating from A Common Trunk: A Rare Anatomical Variant.

Knowledge of the anatomic variations of the supraduodenal artery (SDA) and right gastric artery (RGA) is necessary to reduce the procedure time and radiation exposure dose, as well as to avoid unexpected complications of catheter placement before hepatic arterial infusion chemotherapy. The SDA and RGA most commonly arise from the gastroduodenal artery (GDA) and the proper hepatic artery, respectively; however, they can branch from the left hepatic artery (LHA). In addition, the SDA frequently anastomoses with the RGA and occasionally with the GDA.

The prognostic impact of combined pulmonary fibrosis and emphysema in patients with clinical stage IA non-small cell lung cancer.

Purpose: We evaluated the long-term outcomes of clinical stage IA non-small cell lung cancer (NSCLC) patients with combined pulmonary fibrosis and emphysema (CPFE) who underwent lobectomy.

Methods: We reviewed the chest computed tomography (CT) findings and divided the patients into normal, fibrosis, emphysema and CPFE groups. We evaluated the relationships among the CT findings, the clinicopathological findings and postoperative survival.

A retrospective cohort study of outcome in systemic sclerosis-associated interstitial lung disease.

Background: The relationship between the histological pattern and survival in systemic sclerosis-associated interstitial lung disease (SSc-ILD) is unclear. In patients with SSc-ILD, we investigated whether the clinical data obtained by non-invasive examinations could be used for prognostic evaluation, and attempted to clarify whether complicating acute exacerbation (AE) and the selection of pharmacological therapy were associated with survival.

Methods: Thirty-five patients with SSc-ILD, who had not been diagnosed by surgical lung biopsy were analyzed, retrospectively.

Intrapulmonary foreign body removal under virtual bronchoscopic navigation.

We report a case of successful removal of a pulmonary foreign body (gauze) using 3-dimensional computed tomography (CT) with virtual bronchoscopy. A 70-year-old woman underwent thoracic surgery for tuberculosis approximately 35 years ago. In 2011, she presented with chronic cough and intermittent fever.

Lung CT: Part 1, Mimickers of lung cancer--spectrum of CT findings with pathologic correlation.

Objective: The purpose of this article is to describe CT findings of miscellaneous pulmonary conditions that mimic lung cancers, especially primary cancers, to improve diagnosis of pulmonary lesions. Brief descriptions of patient clinical information and pathologic findings will be included and correlated with imaging findings in actual cases.

Conclusion: A wide variety of pulmonary conditions present imaging features that mimic those of primary lung cancers and are difficult to differentiate from cancer.

Thymic basaloid carcinoma with aggressive invasion of the lung and pericardium: report of a case.

We report a case of basaloid carcinoma of the thymus, invading the lung and pericardium. The patient was a 72-year-old man who suffered thoracic trauma in a fall and was taken to his family physician. Computed tomography revealed a huge mediastinal tumor with cystic components, pressing into the lung.

A case of diffused malignant pleural mesothelioma forming small multiple disseminations with intraoperatively suspicious carcinoid tumors.

A 65-year-old male, having symptoms suggestive of pulmonary malignant tumor, underwent video-assisted thoracic surgery (VATS). Surgery revealed a solid tumor originating from the thoracic wall, with many small solid tumors in the thoracic wall and diaphragm near the tumor. The intraoperative observation of a frozen section typed the tumor as carcinoid; however, hematoxylin-eosin staining and immunohistological findings provided the definitive diagnosis of diffused, malignant pleural mesothelioma (MPM).

Complication of bovine pericardial buttress: pulmonary pseudotumor.

A 38-year-old man reported progressive back pain 4 years after undergoing partial resection of the lung for spontaneous pneumothorax, using staples buttressed with bovine pericardium. Chest computed tomography detected a mass near the staple line. Resection of the mass was performed successfully and the pain was relieved.

Thyroid cancer with a cystic mediastinal tumor invading the right main bronchus.

A 55-year-old woman presented with hemosputum. She had noted thyroid swelling and computed tomography was performed by her family physician. The computed tomographic scan revealed a thyroid tumor and a mediastinal cyst connecting to the thyroid tumor.

Well-differentiated fetal adenocarcinoma of the lung: early-phase sequential high-resolution computed tomographic findings.

Well-differentiated fetal adenocarcinoma is a rare primary adenocarcinoma originating in the lung. We present an early phase case that was followed up for 2 years with chest roentgens and high-resolution computed tomography. Multicentric origin was suspected in the sequential high-resolution computed tomography study findings.

IgG4-positive plasma cells in inflammatory abdominal aortic aneurysm: the possibility of an aortic manifestation of IgG4-related sclerosing disease.

Inflammatory abdominal aortic aneurysm (IAA) is associated with autoimmune disease. However, the precise mechanism of IAA remains unclear. There is increasing evidence that IgG4 is involved in the autoimmune mechanism of various idiopathic sclerosing lesions, including sclerosing pancreatitis and retroperitoneal fibrosis.

Hypogenetic lung syndrome with anomalous venous return to the left inferior pulmonary vein: multidetector row CT findings.

A unique case of hypogenetic lung syndrome is demonstrated with contrast-enhanced multidetector row computed tomography images. This is the first report of hypogenetic lung syndrome with anomalous venous return to the left inferior pulmonary vein.

Possible involvement of myofibroblast in the development of inflammatory aortic aneurysm.

To clarify the role of myofibroblasts in the development of inflammatory aortic aneurysm (IAA), 11 cases of IAA (69.2+/-8.59 years) were investigated immunohistochemically and were morphometrically compared with 12 age-matched cases of atherosclerotic abdominal aneurysm (AAA, 69.
