Microbots show promise in tumor treatment

Targeting medical treatment to an ailing body part is a practice as old as medicine itself. A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside the body and is not so easy to reach. In such cases, a treatment like surgery or chemotherapy might be called for. A pair of researchers in Caltech's Division of Engineering and…

Breast cancer surgery without lab testing and pathology reports may soon be a reality

Determining where breast cancer ends and healthy tissue begins is a critical part of breast cancer surgery. Surgeons are used to working closely during surgery with anatomic pathologists who generate pathology reports that specify the surgical or tumor margin, an area of healthy tissue surrounding a tumor that also must be excised to ensure none of the tumor is left behind. This helps prevent the…

Abundant ultrasound tech potential

Automation continues to conquer healthcare, including diagnostic imaging. Christian Kollmann, Assistant Professor at the Centre for Medical Physics and Biomedical Technology, Medical University Vienna, Austria, highlights innovative software, fast hardware and artificial intelligence in ultrasound – today and in the future. Automated analyses are already supporting the diagnostic work-up. In…

Promising option for noninvasive monitoring of prostate cancer

While active surveillance is often recommended for patients with nonaggressive prostate cancer to reduce unnecessary treatment, the challenge for clinicians is to monitor and distinguish early-stage tumors from advanced cancers. A team of scientists led by researchers from Roswell Park Cancer Institute have demonstrated that photoacoustic imaging (PAI) may be an effective tool for more accurately…

Molecular imaging mines deeper

The view across the Atlantic – it fills Professor Fabian Kiessling, Chair of Experimental Molecular Imaging at the RWTH Aachen (Rhine-Westphalia Institute of Technology Aachen), with optimism. The USA offers more opportunities for molecular imaging. Only recently, new tracers for Alzheimer’s were accepted as reimbursable in some centres, whilst the development of new diagnostics in Europe…

A new imaging tool?

Mammography is the common way to detect breast cancer. But it's not perfect: it struggles to image dense glandular tissue or early-stage tumours. Magnetic resonance imaging (MRI) offers best sensivity but it is expensiv and not always specific enough. Now researchers have come up with another option: a scanner that integrates thermoacoustic and photoacoustic tomography to achieve dual-contrast…
