Radiographic Analysis of Scoliosis Using Convolutional Neural Network in Clinical Practice.

Purpose: To assess the reliability and accuracy of an automated Cobb angle measurement (ACAM) using a convolutional neural network (CNN) for scoliosis evaluation and to compare measurement times.

Materials And Methods: ACAM was applied to spine radiographs in 411 patients suspected of scoliosis. Observer 1 (consensus of two musculoskeletal radiologists) and observer 2 (a radiology resident) measured Cobb angle (CA).

Comparison of Diagnostic Performance in Mammography Assessment: Radiologist with Reference to Clinical Information Versus Standalone Artificial Intelligence Detection.

We compared diagnostic performances between radiologists with reference to clinical information and standalone artificial intelligence (AI) detection of breast cancer on digital mammography. This study included 392 women (average age: 57.3 ± 12.

Artificial Intelligence for Breast Cancer Screening in Mammography (AI-STREAM): A Prospective Multicenter Study Design in Korea Using AI-Based CADe/x.

Purpose: Artificial intelligence (AI)-based computer-aided detection/diagnosis (CADe/x) has helped improve radiologists' performance and provides results equivalent or superior to those of radiologists' alone. This prospective multicenter cohort study aims to generate real-world evidence on the overall benefits and disadvantages of using AI-based CADe/x for breast cancer detection in a population-based breast cancer screening program comprising Korean women aged ≥ 40 years. The purpose of this report is to compare the diagnostic accuracy of radiologists with and without the use of AI-based CADe/x in mammography readings for breast cancer screening of Korean women with average breast cancer risk.

Breast adenoid cystic carcinoma arising in microglandular adenosis: A case report and review of literature.

Background: Breast adenoid cystic carcinoma (AdCC) is a rare invasive carcinoma composed of epithelial and myoepithelial cells. Microglandular adenosis (MGA) is a rare benign proliferative lesion consisting of small, uniform, and round glands formed by a single layer of epithelial cells and basement membrane without a myoepithelial cell layer. MGA may progress to atypical MGA and carcinoma arising in MGA.

Primary pleural epithelioid angiosarcoma manifesting as a loculated hemothorax: A case report and literature review focusing on CT findings.

Primary pleural angiosarcoma (PPA) is an extremely rare and clinically aggressive tumor. We report the case of a 66-year-old man having PPA with chest computed tomography (CT) scan showing a large oval-shaped, nonenhancing high attenuation cystic mass in the left hemithorax. Morphological and immunohistochemical findings supported the diagnosis of epithelioid angiosarcoma.

The 8-Year Management of an Older Breast Cancer Patient by Non-surgical Primary Therapies and Minimized Surgery: A Case Report.

A 74-year-old woman presented with a palpable lesion in her right breast. At the time of her visit, she was taking medications for diabetes, hypertension, tremors, tinnitus, and lumbago. She was also caring for her husband, who had dementia.

Ultrasonographic Features and the Diagnostic Role of Core Needle Biopsy at Metastatic Breast Cancer in the Thyroid gland: A Case Report.

Metastases to the thyroid gland have rarely been reported in clinical settings, and the thyroid gland is an uncommon site for breast carcinoma metastasis. We report a case of a 64-year-old breast cancer patient diagnosed with metastatic breast carcinoma in the thyroid gland after performing ultrasonography (US)-guided core needle biopsy (CNB) and subsequent total thyroidectomy. On US, the thyroid lesion appeared to be mildly enlarged with multiple internal hypoechoic lines and a few microcalcifications without mass formation.

Malignant sweat gland tumor of breast arising in pre-existing benign tumor: A case report.

Background: Sweat glands belong to skin appendages. Sweat gland tumors are uncommon, especially when they occur as malignant tumors in the breast. We report a case of malignant sweat gland tumor of the breast, including imaging and pathological findings.

A Pulmonary Sequestered Segment with an Aberrant Pulmonary Arterial Supply: A Case of Unique Anomaly.

We presented a rare case of a 64-year-old man with a combined anomaly of the bronchus and pulmonary artery that was detected incidentally. Computed tomography showed a hyperlucent, aerated sequestered segment of the right lower lung with an independent ectopic bronchus, which had no connection to the other airway. The affected segment was supplied by its own aberrant pulmonary artery branch from the right pulmonary trunk.

Non-puerperal mastitis masking pre-existing breast malignancy: importance of follow-up imaging.

Mastitis is an inflammatory condition of the breast with common symptoms of pain, swelling, erythema, warmth, and fever. Diagnosis of mastitis is easily made on the basis of typical symptoms and ultrasonographic findings, such as diffusely increased echogenicity of the parenchyma and subcutaneous fat, or skin thickening. However, when it occurs in women middle-aged or older, associated malignancy should be considered.

Anomalous origin of the right pulmonary artery from the ascending aorta associated with patent ductus arteriosus: focusing on computed tomography findings.

Anomalous origin of one pulmonary artery from the ascending aorta (AOPA) is a rare congenital malformation. Fewer than 150 cases have been reported to date in the world, with 95 % of these documented during the first year of the patient's life. We encountered a rare case of AOPA associated with patent ductus arteriosus in a 41-year-old female, who had reached the most advanced age of any known, previously untreated AOPA patient.

Small-cell neuroendocrine carcinoma of the breast.

A small-cell carcinoma is one of the histologic subtypes of primary neuroendocrine carcinomas of the breast. A small-cell carcinoma is a rare entity of the breast and exhibits similar morphologic features as neuroendocrine tumors of the gastrointestinal tract and lung. We present the imaging and pathologic findings of a primary small-cell neuroendocrine carcinoma of the breast.

Quercetin suppresses HeLa cell viability via AMPK-induced HSP70 and EGFR down-regulation.

Quercetin, an anti-oxidant flavonoid that is widely distributed in the plant kingdom, has been suggested to have chemopreventive effects on cancer cells, although the mechanism is not completely understood. In this study, we found that quercetin increased the phosphorylation of AMP-activated protein kinase (AMPK) and downstream acetyl-CoA carboxylase (ACC) and suppressed the viability of HeLa cells. AICAR, an AMPK activator, and quercetin down-regulated heat shock protein (HSP)70 and increased the activity of the pro-apoptotic effector, caspase 3.

Acute obstructive cholangitis after transarterial chemoembolization: the effect of percutaneous transhepatic removal of tumor fragment.

Acute obstructive cholangitis due to the migration of necrotized tumor fragment is a rare complication occurring after a transarterial chemoembolization. The percutaneous tumor removal procedure following percutaneous transhepatic biliary drainage is an appropriate treatment over endoscopic removal for the relief of acute cholangitis in this case. Following this serial management, no invasive hepatocellular carcinoma of the bile duct recurred after two years of follow-up.

Malignant fibrous histiocytoma of chest wall.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is rare. We report a case of primary MFH arising from the chest wall, which was thought to be a metastasis or myeloma. The imaging study revealed a single mass of the chest wall involving a rib.
