Noninvasive Tests to Monitor Methotrexate‐Induced Liver Injury

Noninvasive Glucose Monitor

Noninvasive tests for liver disease, fibrosis, and cirrhosis: Is liver biopsy obsolete?

Liver biopsy has been used to diagnose chronic liver disease and to assess the degree of hepatic inflammation and fibrosis. However, it is an invasive test with many possible complications and the potential for sampling error. Noninvasive tests are increasingly precise in identifying the cause of many cases of liver disease and even the amount of liver injury (fibrosis). This review discusses t...

A noninvasive multimodal technique to monitor brain tumor vascularization.

Determination of tumor oxygenation at the microvascular level will provide important insight into tumor growth, angiogenesis, necrosis and therapeutic response and will facilitate to develop protocols for studying tumor behavior. The non-ionizing near infrared spectroscopy (NIRS) technique has the potential to differentiate lesion and hemoglobin dynamics; however, it has a limited spatial resol...

A novel noninvasive blood glucose monitor.

OBJECTIVE To evaluate the precision and accuracy of a new advanced prototype of a noninvasive blood glucose monitor across a wide range of serum glucose concentrations. RESEARCH DESIGN AND METHODS An advanced handheld noninvasive glucose monitor prototype was calibrated and tested using patients recruited by the General Research Center of the University of Connecticut Health Center. The monit...

Esophageal Doppler: noninvasive cardiac output monitor.

In this article we describe the esophageal Doppler, a noninvasive, instantaneous cardiac output monitor. Its reliability has been demonstrated to be comparable to that of other current techniques used in the clinical arena to measure cardiac output. It helps guiding intravascular fluid resuscitation by quantifying the increase in flow in response to fluid challenges and by indicating the platea...
