Prostate cancer (PCa) remains a significant health concern, and the accurate diagnosis and characterisation of its severity are crucial for effective treatment. Currently, biopsy and multiparametric MRI (mpMRI) are standard diagnostic tools, though they are limited in sensitivity and specificity. A novel approach using Sodium-23 (23Na) MRI has...Read more

Oncologic PET/CT imaging plays a critical role in the diagnosis, treatment planning, and monitoring of cancer patients. However, one of the significant challenges in PET/CT is the time dependence of traditional metrics like Standardised Uptake Value (SUV). This time dependence can introduce variability in tracer uptake measurements, affecting...Read more

The global demand for imaging tests to assess cancer is increasing, but there's a shortage of imaging specialists, particularly in low and middle-income countries. This leads to delays in scan reporting and patient management. Artificial intelligence (AI) using deep neural networks (DNNs) could help handle high scan volumes while maintaining diagnostic...Read more

Breast density is recognised as a risk factor for breast cancer, and dense breast tissue can decrease mammographic sensitivity, leading to diagnostic delay . This is of particular concern to women in their 40s and 50s , for whom the prevalence of dense breasts ranges from 38% to 57%. Concerns about the low sensitivity of screening mammography...Read more

Scientists from Tomsk Polytechnic University, Tomsk Research Institute of Oncology and the Institute of Biorganic Chemistry of the Russian Academy of Sciences have developed a radiopharmaceutical for advanced identification of cancer. Labelled as the technetium-99 isotope, the medication is ready for pre-clinical phase trial. The radiopharmaceutical...Read more

We've all seen computer programmes defeat humans in Chess, Jeopardy and other similar games but now a programme has outperformed physicians at brain cancer diagnoses. Developed at Case Western Reserve University, this computer programme turned out to be twice as accurate as two neuroradiologists in determining whether abnormal tissue on MRI were...Read more

Scientists at the research Institute MIRA at the University of Twente in the Netherlands have developed PAMmograph, a new technique to detect breast cancer. PAMmography is based on the physical principle of photoacoustics and uses short bursts of light that cause ultrasonic waves to be generated in places with high density of blood vessels. Details...Read more

A new self-assembling nanoparticle has been designed to allow. the ability to diagnose cancer earlier. Developed by a team of researchers at Imperial College London, this new nanoparticle seeks out receptors in cancerous cells, thus boosting the effectiveness of MRI scanning. It is coated with a special protein that detects signals given off by tumours....Read more
