This early study tests a special PET/MRI scan using a radioactive tracer called FET to find small pituitary tumors that don't show up on regular MRI. The goal is to improve detection of these hormone-producing tumors in 5 adults with confirmed biochemical disease. If the scan wor…

This study tests a device called the CONVIVO system, which acts like a high-powered microscope during brain tumor surgery. It helps surgeons tell the difference between normal and abnormal tissue right away. About 30 adults with various brain tumors will take part. The goal is to…

This study tests a new ultrasound method to help surgeons find pituitary tumors during surgery. Researchers will compare ultrasound images with MRI scans to see if the new technique can better identify tumors in people with Cushing's disease and other pituitary tumors. About 110 …

This pilot study at the University of Cambridge is testing whether a new PET scan tracer called FET can locate pituitary tumors as well as the standard tracer, methionine. The study involves 20 adults with suspected pituitary adenomas who have already had a methionine PET scan. I…

This study tests whether a special PET/MRI scan using a radioactive tracer called Ga68-DOTATATE can better detect certain brain tumors (like meningioma) and tell them apart from changes caused by past treatments. About 200 adults with these tumors will get the scan alongside stan…

This trial tests a new anti-fog suction device that keeps the camera lens clear during nose-to-pituitary tumor surgery. Twenty adults with pituitary or craniopharyngioma tumors will either get the device or the usual water-squirt method. The goal is to see if the device reduces f…

This study tests whether a nerve block (injecting numbing medicine near a nerve cluster in the face) can improve the surgical view and reduce pain for people having pituitary tumor surgery through the nose. 70 adults will be randomly assigned to receive either the nerve block plu…
