Article Synopsis
- The study discusses advancements in photoacoustic tomography (PAT) for visualizing microvascular structures, essential for assessing conditions like diabetes and inflammatory skin diseases.
- By improving the scanner's speed from minutes to mere seconds or milliseconds, the authors enable better visualization with less motion-related interference and detailed 3D imaging.
- These enhancements allow for the exploration of microvascular changes in various medical conditions, suggesting potential applications in fields such as cardiovascular medicine, oncology, dermatology, and rheumatology.
Combining optoacoustic (OA) imaging with ultrasound (US) enables visualisation of functional blood vasculature in breast lesions by OA to be overlaid with the morphological information of US. Here, we develop a simple OA feature set to differentiate benign and malignant breast lesions. 94 female patients with benign, indeterminate or suspicious lesions were recruited and underwent OA-US.

Multispectral optoacoustic tomography (MSOT) is a type of optoacoustic imaging system that has seen promising preclinical success with a recent emergence into the clinic. Multiwavelength illumination of tissue allows for the mapping of multiple chromophores, which are generated endogenously or exogenously.
View Article and Find Full Text PDFThis review identifies and examines terms used to describe a radiological research "study" or "trial". A taxonomy of clinical research descriptions is explained with reference to medical imaging examples. Because many descriptive terms have precise methodological implications, it is important that these terms are understood by readers and used correctly by researchers, so that the reader is not misled.

Material And Methods: Indexed studies describing themselves as a "pilot" in their title were identified from four indexed radiological journals. The aim was to identify 20 consecutive, eligible studies from each journal, as this sample size was deemed sufficient to be representative as to how this methodological description was employed by authors of radiological articles.
