Artificial intelligence models for the diagnosis and management of liver diseases. Ultrasonography (IF 3.1) Pub Date : 2022-09-06 Naoshi Nishida,Masatoshi Kudo
With the development of more advanced methods for the diagnosis and treatment of diseases, the data required for medical care are becoming complex, and misinterpretation of information due to human error may result in serious consequences. Human error can be avoided with the support of artificial intelligence (AI). AI models trained with various medical data for diagnosis and management of liver diseases

Follow-up of benign thyroid nodules confirmed by ultrasound-guided core needle biopsy after inconclusive cytology on fine-needle aspiration biopsy. Ultrasonography (IF 3.1) Pub Date : 2022-09-21 Yoon Ji Hwang,Hye Ryoung Koo,Jeong Seon Park
PURPOSE The goal of this study was to follow benign thyroid nodules confirmed by ultrasound (US)-guided core needle biopsy (CNB) after inconclusive cytology on fine-needle aspiration (FNA) biopsy. METHODS Sixty-two thyroid nodules from 62 patients with CNB-confirmed benign histology that initially had inconclusive cytology on FNA were retrospectively included. The thyroid nodules were followed for

US features of normal parathyroid glands: a comparison with metastatic lymph nodes in thyroid cancer. Ultrasonography (IF 3.1) Pub Date : 2022-09-06 Seong Ju Kim,Dong Gyu Na,Byeong-Joo Noh
PURPOSE This study aimed to determine the ultrasound (US) features of normal parathyroid glands (PTGs) and to evaluate whether normal PTGs can be differentiated from metastatic lymph nodes (LNs) in thyroid cancer. METHODS This retrospective study included 10 normal PTGs and 95 metastatic LNs from thyroid cancer showing suspicious US features. The echogenicity, echotexture, echogenic foci (calcifications)
