Optical coherence tomography (OCT) has become one of the most successful optical technologies implemented in medicine and clinical practice mostly due to the possibility of non-invasive and non-contact imaging by detecting back-scattered light. OCT has gone through a tremendous development over the past 25 years. From its initial inception in 1991 [Science254, 1178 (1991)] it has become an indispensable medical imaging technology in ophthalmology. Also in fields like cardiology and gastro-enterology the technology is envisioned to become a standard of care...

In this chapter, we describe two new methodologies: (1) application of high-frequency ultrasound spectroscopy for in vivo detection of cancer cell death in small animal models, and (2) extension of ultrasound spectroscopy to the lower frequency range (i.e., 1-10 MHz range) for the detection of cell death in vivo in preclinical and clinical settings. Experiments using tumor xenografts in mice and cancer treatments based on chemotherapy are described. Finally, we describe how one can detect cancer response to treatment in patients noninvasively early (within 1 week of treatment initiation) using low-frequency ultrasound spectroscopic imaging and advanced machine learning techniques...

INTRODUCTION: Hybrid imaging has proven to be a major innovation in nuclear medicine, allowing the fusion of functional information with anatomical detail. In the past, the use of hybrid imaging such as PET-CT, PET-MRI and SPECT-CT has been of great clinical benefit; however, these scanners are relatively large and bulky. We have developed and investigated the clinical application of a compact small field of view hybrid gamma camera (HGC) that is suitable for small-organ imaging at the patient bedside...

PURPOSE: Shared decision-making, when physicians and patients collaborate and agree on health care decisions, is a key tenant of patient-centered care. Choice of access site for neurovascular procedures is rarely a shared decision point between physicians and patients. We present our initial evaluation of patient preference for radial over femoral access for cerebrovascular procedures. MATERIALS AND METHODS: IRB approved single-center, prospective, and consecutive survey of all patients undergoing transradial access for cerebrovascular imaging and intervention...

In tumor diagnostics, especially in the staging diagnostic of tumor patients, ultrasound is predominantly an additive method in the age of modern imaging (CT/MRT/PET-CT), because of the limitation by interobserver variability and poor sound conditions. The aim of this thesis is to elaborate specific oncological questions on the sonography and to describe the requirements for sonography and the importance of the method in the diagnosis of tumor diseases in the age of CT, MRT and PET-CT. In general, the requirements on the sonography must be differentiated between primary diagnosis, staging diagnostic, treatment response, and tumor aftercare...

Trachelospermum jasminoides is commonly used in traditional Chinese medicine. However, the use of the plant's local alternatives is frequent, causing potential clinical problems. The T. jasminoides sold in the medicine market is commonly dried and sliced, making traditional identification methods difficult. In this study, the ITS2 region was evaluated on 127 sequences representing T. jasminoides and its local alternatives according to PCR and sequencing rates, intra- and inter-specific divergences, secondary structure, and discrimination capacity...

The evolution of modern medicine largely influenced the development of new postgraduate training programs, which requirements are more engaging and constraining. Time dedicated to education more and more often comes into competition with the resident's clinical and administrative activities. In this context, E-learning could be an interesting solution, if used complementary to the classical training which does not further overload the clinical activity. By focusing on the recognition of clinical images, and interpretation of functional tests, we target some well known knowledge gaps of our trainees...

Advances in technology are revolutionizing medicine and the limits of what we can offer to our patients. In neurosurgery, technology continues to reduce morbidity, increase surgical accuracy, facilitate tissue acquisition, and promote novel techniques for prolonging survival in patients with neuro-oncologic disease. Surgery has been the backbone of glioma diagnosis and treatment by providing adequate, high quality material for precise histologic diagnosis, and genomic characterization in the setting of significant intratumoral heterogeneity, thus allowing personalized treatment selection in the clinic...

C Stelzner, N Abolmaali, U Hecker, S Schellong
Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound...

Cell fate is a concept used to describe the differentiation and development of a cell in its organismal context over time. It is important in the field of regenerative medicine, where stem cell therapy holds much promise but is limited by our ability to assess its efficacy, which is mainly due to the inability to monitor what happens to the cells upon engraftment to the damaged tissue. Currently, several imaging modalities can be used to track cells in the clinical setting; however, they do not satisfy many of the criteria necessary to accurately assess several aspects of cell fate...
