Abstract: In accordance with some embodiments, systems, methods, and media for automatically predicting a classification of incidental adrenal tumors based on clinical variables and urinary steroid levels are provided. In some embodiments, the system comprises: a processor programmed to: generate a feature vector including clinical variables and biomarker levels associated with the patient presenting with an unclassified adrenal mass; provide the feature vector to a machine learning model trained using a labeled feature vectors associated patients having adrenal masses classified as benign, adrenal cortical carcinoma, or another malignant adrenal mass; receive, from the trained machine learning model, an output indicative of a classification of the unclassified adrenal mass; and cause information indicative of the classification to be presented to a user to aid the user in classification of the unclassified adrenal mass.

Abstract: A probe for an NMR device is disclosed in which a saddle coil is disposed on one side of a flexible insulating material, and an additional conductor is disposed on the opposite side. The additional conductor and the conductors of the saddle coil create a capacitance across the insulating material. This capacitance acts with the inductance of the saddle coil such that the probe itself forms a transmission line. The probe is thus inherently broadband and requires no tuning. It also presents a constant impedance, thus facilitating impedance matching to an NMR spectrometer. In a preferred embodiment, a chip resistor is disposed on the flexible insulating material, terminating the transmission line.
