MRI in Pulmonary Embolism Diagnosis

2017 25 Apr

  Magnetic resonance imaging (MRI) has high specificity but limited sensitivity for the diagnosis of pulmonary embolism (PE), according to a systematic review published in the journal Thrombosis Research. Given these inconclusive results, researchers say management studies are needed to more precisely define the role of MRI in the diagnostic workup... Read more

Sestamibi SPECT/CT Scan Improves Kidney Cancer Diagnosis

2017 21 Apr

According to results from a series of studies led by researchers at Johns Hopkins Medicine, the addition of a noninvasive imaging test called 99mTc-sestamibi SPECT/CT to CT or MRI increases the accuracy of kidney tumour classification. The researchers believe that using this test could improve diagnostic accuracy and could spare thousands of patients... Read more

MRI Improves Diagnosis of Fetal Brain Abnormalities

2016 19 Dec

New research published in The Lancet suggests that adding MRI after the mid-pregnancy scan could provide more certainty in diagnosing fetal brain abnormalities. The study involved 570 women whose mid-pregnancy ultrasound scan revealed a potential brain abnormality in the fetus. Within two weeks of their first scan they were given an extra scan using...
