Machine learning techniques generate clinical labels of medical scans

(The Mount Sinai Hospital / Mount Sinai School of Medicine) Researchers used machine learning techniques, including natural language processing algorithms, to identify clinical concepts in radiologist reports for CT scans.

Posterior malleolar fractures (PMFs) have been demonstrated to result in poorer outcomes than other types of ankle fractures with a higher incidence of posttraumatic arthritis. Accordingly, there has been a recent surge in interest in reduction and fixation of PMFs. Operative criteria for PMFs have been based on size, step-off, ankle joint instability, and syndesmotic injury, though universally accepted criteria have yet to be defined. Anatomically, the posterior malleolus is important as an insertion point of the posterior inferior tibiofibular ligament and thereby may play a role in syndesmotic stability. However, the im...

This study therefore evaluates the compatibility bioleaching microorganisms with X-ray energy exposure. The X-ray effect on a mixed thermophilic culture suspended in solution was assessed using imaging conditions of 35-150 kV, 200-280 µA and 1-2 hours. Microorganisms were unaffected between 35-90 kV and 200-280 µA while there was some detrimental effect at 120 and 150 kV. The X-ray influence on a mixed mesophilic culture colonising a mineral surface was investigated at 90 kV and 225 µA for a 1 hour exposure time. The system was monitored befor...

ConclusionCervical incidentalomas vary in rates from ARSA (0.86%) to LC (9.4%). They are rarely mentioned in radiologists ’ reports. Whether improved vigilance and reporting of these incidentalomas would benefit patient care should be explored.

Publication date: Available online 20 August 2018Source: NeurocomputingAuthor(s): Junjie Zhang, Yong Xia, Haoyue Zeng, Yanning ZhangAbstractDetection of pulmonary nodules on chest CT is an essential step in the early diagnosis of lung cancer, which is critical for best patient care. In this paper, we propose an automated pulmonary nodule detection algorithm, denoted by NODULe, which jointly uses a conventional method for nodule detection and a deep learning model for genuine nodule identification. Specifically, we first use multi-scale Laplacian of Gaussian (LoG) filters and prior shape and size constraints to detect nodul...

This study aimed to compare the clinical effectiveness of urine exfoliated cells FISH examination, CT scan, and urine cytologic examination on the diagnosis of upper urinary tract urothelium carcinoma with hematuresis symptom. MATERIAL AND METHODS A total of 30 patients with suspicious upper urinary tract urothelium carcinoma between Aug 2010 and Aug 2011 were enrolled, including 23 males and 7 females. All the subjects received urine exfoliated cells FISH examination, CT scan, and urine cytologic examination. Twenty-one cases were diagnosed as urothelium carcinoma, including 14 cases of carcinoma of renal pelvis and 7 cas...

ConclusionSimultaneous resection of synchronous adenocarcinoma of the cardia and the sigmoid is feasible and avoids possible progression of the untreated neoplasm during the interval between two separate resections, provided that a curative resection can be obtained for both diseases.

ConclusionFor the CBCT model used in this study, optimization implies the use of the highest kV along with the shortest exposure time and a task-specific mA. The proposed step-wise optimization approach could be applied to any CBCT unit, preferably during commissioning.
