Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Diagnosis / Prognosis - T2 magnetic resonance

Diagnosis / Prognosis: T2 magnetic resonance
Samples for assessment by the T2MR will be collected once daily in occasion of any consecutive febrile episode during neutropenia when blood cultures are ordered as per standard of care. T2 magnetic resonance will be run according to manufacturer's instructions

Summary
Brief summary
Mortality due to bloodstream infections in patients with neutropenia and haematological
malignancies is high and optimal management is hampered by long turnaround times of
conventional blood cultures.

This is an observational study to assess the performance of T2 magnetic resonance, in
diagnosing proven, probable and possible bloodstream infections as well as its theoretical
impact on antimicrobial prescriptions in neutropenic patients with acute leukemia and bone
marrow recipients.
