Slicing through an orange to expose its tiny juice-filled pockets arranged in petal-like segments is thrilling, but destroys the orange orb forever. An alternative is to visualise ultra-thin sections of the tangy treat using Magnetic Resonance Imaging (MRI) (pictured). This leaves the fruit untouched, but reveals every bite of beauty within. MRI scanning is the technology of choice for doctors homing in on tumours in patients with suspected cancer. Inside the scanner, patients – like these fruit – are exposed to a strong magnetic field and radio waves. The waves bounce off tissues and emit signals that computers translate into detailed pictures. But until now MRIs could not reveal brain tumours until they reached the size of a plum stone, often too big to treat effectively. With sensitive MRI techniques coming to fruition, they will cut the size of a detectable brain tumour to little larger than a tomato seed.

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
