Decision aids quickly and accurately rule out heart attack for almost half of all patients tested

Decision aids provided immediate reassurance to almost half of all patients arriving at emergency departments with a suspected heart attack. Use of the aids, which are based on a single blood test, accurately ruled out heart attacks in patients with relevant symptoms. Aids could provide early reassurance for worried patients and families and avoid many ...

A simple test may predict the risk of hospitalisation for flare-up in patients with COPD, a common lung disease

The sit-to-stand test, which requires only a chair and a stopwatch, could identify patients with a common lung disease who are at high risk of being admitted to hospital. Researchers found that the test, which takes less than five minutes to perform, also predicted the length of their hospital stay. The study looked at patients ...

Cancer screening across the world is failing people with mental illness

People with mental illness are nearly 25% less likely to receive cancer screening than those in the general population. Results from a large international study suggest this is one explanation for why people with mental illness tend to die 15-20 years earlier than other people. The study included more than 4.5 million people across the ...

Universal ultrasound in late pregnancy did not reduce serious harms to babies

Offering all women third trimester ultrasounds did not reduce the rate of serious illness or death in babies in the first week of life. Monitoring fetal growth is part of routine antenatal care, using regular tape measurements from the pubic bone to the top of the uterus. To date, it has been unclear whether also ...

Antenatal MRI can aid ultrasound when fetal brain abnormality is suspected

In utero magnetic resonance imaging (iuMRI) can provide a more accurate diagnosis when used after ultrasound in pregnancy. Adding iuMRI when a brain abnormality is suspected but unclear from ultrasound could help clinicians provide better prognostic advice and support to parents during pregnancy. This NIHR-funded cohort study compared ultrasound and iuMRI in 570 women at ...

MRI and ultrasound scans are both helpful in assessing Crohn’s disease; MRI is slightly more accurate

Two types of scan, MRI and ultrasound, work well when used for staging and monitoring Crohn’s disease. MRI is more accurate. Researchers compared a form of magnetic resonance (MR) imaging that includes an oral contrast agent, with ultrasound scans. They aimed to see which was better able to detect the presence and extent of active ...

Diagnosis of delirium in hospitals can be improved by the 4 A’s test

A new shorter test for delirium appears helpful in assessing older people in hospital who may have the condition. A normal score on the 4 A’s test effectively rules out delirium while an abnormal score is reasonably useful for detecting the condition. People detected by the test would still need a full assessment to confirm ...

Whole-body MRI is effective for identifying metastatic disease in colorectal cancer patients

Initial investigation which includes whole-body magnetic resonance imaging (MRI) is as good as standard pathways for detecting metastatic disease in adults with newly diagnosed colorectal cancer. This NIHR-funded study also found that whole-body MRI reduces the number of investigations needed, the length of the staging process, and costs less than standard pathways. The treatment options ...

Whole-body MRI scans are as accurate as standard imaging pathways for lung cancer staging

Using whole-body magnetic resonance imaging (MRI) in the initial investigation pathway is as good as standard pathways for detecting metastatic disease in adults with non-small-cell lung cancer. This NIHR-funded study also found that WB-MRI used for diagnosis and staging is quicker, cheaper and requires fewer other investigations than standard pathways. Although patients reported that having ...

Transvaginal ultrasound and MRI achieve similar accuracy for diagnosing lower bowel endometriosis

Transvaginal ultrasound and magnetic resonance imaging (MRI) scans are both accurate ways to diagnose the most severe form of deep endometriosis affecting the bowel. By using both transvaginal ultrasound and MRI, the chance of non-invasively and accurately diagnosing endometriosis of the lower bowel rises to nearly 100%. This review and meta-analysis looked at eight studies ...
