TL;DR: The actual use of these powerful new tools has been propelled most recently by the results of several clinical trials that have changed the approach to patients with carotid occlusive disease, thus greatly expanding the need for neurovascular imaging.
Abstract: Studying the cervicocranial vasculature in a noninvasive fashion has been a major focus of imaging technology for some time. Over the past two decades, a number of new imaging techniques have been developed and applied to this purpose. Some, like intravenous digital subtraction angiography, have failed to meet the test of utility despite their feasibility. By the mid-1990s, however, at least three methods of noninvasive imaging have been refined to the degree that they now rival conventional intraarterial angiography in accuracy (at least in limited segments of the anatomy). Magnetic resonance (MR) angiography, Doppler sonography, and, most recently, computed tomographic (CT) angiography are now robust techniques. MR angiography and Doppler sonography have already achieved wide popularity, while the growth of CT angiography has been limited by the relatively slow introduction of slip-ring CT technology, its dependence on intravenous bolus injection of iodinated contrast material, and the preexisting presence of two formidable rivals in the field. The actual use of these powerful new tools has been propelled most recently by the results of several clinical trials that have changed the approach to patients with carotid occlusive disease, thus greatly expanding the need for neurovascular imaging.

TL;DR: Any attempt to understand imaging technology must place at its centre the perspectives of patients and radiographers, and it is suggested that scientific descriptors must be balanced with equal deliberation given to ‘soft technology'.

TL;DR: The primary objective of this overview is to apprise clinical urologists and oncologists of the current state of fused multimodality imaging of prostate cancer, which can be applied to optimize treatment by ensuring that a patient's disease is characterized as well as current imaging technology permits.

TL;DR: Historical and scientific guidance on imaging response assessment for incorporation into clinical trials to stimulate effective and expedited drug development for recurrent glioblastoma is provided.
Abstract: We provide historical and scientific guidance on imaging response assessment for incorporation into clinical trials to stimulate effective and expedited drug development for recurrent glioblastoma by addressing 3 fundamental questions: (i) What is the current validation status of imaging response assessment, and when are we confident assessing response using today's technology? (ii) What imaging technology and/or response assessment paradigms can be validated and implemented soon, and how will these technologies provide benefit? (iii) Which imaging technologies need extensive testing, and how can they be prospectively validated? Assessment of T1 +/− contrast, T2/FLAIR, diffusion, and perfusion-imaging sequences are routine and provide important insight into underlying tumor activity. Nonetheless, utility of these data within and across patients, as well as across institutions, are limited by challenges in quantifying measurements accurately and lack of consistent and standardized image acquisition parameters. Currently, there exists a critical need to generate guidelines optimizing and standardizing MRI sequences for neuro-oncology patients. Additionally, more accurate differentiation of confounding factors (pseudoprogression or pseudoresponse) may be valuable. Although promising, diffusion MRI, perfusion MRI, MR spectroscopy, and amino acid PET require extensive standardization and validation. Finally, additional techniques to enhance response assessment, such as digital T1 subtraction maps, warrant further investigation.

TL;DR: In this paper, the authors present the research status and prospects of several common continuous-wave (CW) terahertz medical imaging systems and applications of THz medical imaging in biological tissues.
Abstract: In the past few decades, the applications of terahertz (THz) spectroscopy and imaging technology have seen significant developments in the fields of biology, medical diagnosis, food safety, and nondestructive testing. Label-free diagnosis of malignant tumours has been obtained and also achieved significant development in THz biomedical imaging. This review mainly presents the research status and prospects of several common continuous-wave (CW) THz medical imaging systems and applications of THz medical imaging in biological tissues. Here, we first introduce the properties of THz waves and how these properties play a role in biomedical imaging. Then, we analyse both the advantages and disadvantages of the CW THz imaging methods and the progress of these methods in THz biomedical imaging in recent ten years. Finally, we summarise the obstacles in the way of the application of THz bio-imaging application technology in clinical detection, which need to be investigated and overcome in the future.
