Clinical Trials [268 Associated Clinical Trials listed on BioPortfolio]

Effect of Respiratory Motion on Positron Emission Tomography Imaging

This study will determine how breathing motions may affect positron emission tomography (PET) scans. It has been discovered that the quality of PET scans varies according to which part of ...

A Prospective Trial to Compare Deep Inspiratory Breath Hold (DIBH) With Prone Breast Irradiation

This phase II trial studies how well deep inspiratory breath hold or prone breast radiation therapy works in reducing cardiac dose in patients with breast cancer or ductal carcinoma in sit...

Breathing Cycle Biofeedback During Computed Tomography Procedures

This study will evaluate the effectiveness of a flexible belt device in guiding patient breathing during computed tomography (CT)-guided needle biopsy. When patients undergo CT scanning t...

Prospective Assessment of Radiation-induced Heart Injury in Left-sided Breast Cancer

This study is to prospectively investigate the cardiac dose-sparing effect and clinical benefit of deep inspiration breath-hold (DIBH) technique. Patients with left-sided breast cancer tre...

Breath-hold Cardiac Hybrid SPECT/CCTA

This study aims at combining inspiration breath-hold myocardial perfusion SPECT with coronary CT angiography.

Effects of intrathoracic pressure, inhalation time, and breath hold time on lung diffusing capacity.

The single breath hold maneuver for measuring lung diffusing capacity for carbon monoxide (DLCO) and nitric oxide (DLNO) incorporates multiple sources of variability. This study examined how changes i...

The Breath-Hold Acceleration Index: A New Method to Evaluate Cerebrovascular Reactivity using Transcranial Doppler.

Cerebrovascular reactivity (CR) is an ideal biomarker to detect cerebrovascular damage. CR can be quantified by measuring changes in cerebral blood flow velocity (CBFV) resulting from a CO vasodilato...

Modified breath-hold compressed-sensing 3D MR cholangiopancreatography with a small field-of-view and high resolution acquisition: Clinical feasibility in biliary and pancreatic disorders.

Compressed-sensing (CS) accelerated 3D MR cholangiopancreatography (MRCP) could be acquired in both navigator-triggered (NT) and breath-hold (BH) mode, but the latter has been considered inferior in d...

Assessment of deep inspiration breath hold (DIBH) amplitude and reduction in cardiac dose in left breast cancer patients.

The primary aim of this study was to examine the impact of deep inspiration breath-hold (DIBH) amplitude on subsequent mean heart dose and V30 during radiotherapy. The secondary aim was to investigate...

Quantifying esophageal motion during free-breathing and breath-hold using fiducial markers in patients with early-stage esophageal cancer.

Cardiac toxicity after definitive chemoradiotherapy for esophageal cancer is a critical issue. To reduce irradiation doses to organs at risk, individual internal margins need to be identified and mini...

Medical and Biotech [MESH] Definitions

External devices which hold wires or pins that are placed through one or both cortices of bone in order to hold the position of a fracture in proper alignment. These devices allow easy access to wounds, adjustment during the course of healing, and more functional use of the limbs involved.

A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.

The vital life force in the body, supposedly able to be regulated by acupuncture. It corresponds roughly to the Greek pneuma, the Latin spiritus, and the ancient Indian prana. The concept of life-breath or vital energy was formulated as an indication of the awareness of man, originally directed externally toward nature or society but later turned inward to the self or life within. (From Comparison between Concepts of Life-Breath in East and West, 15th International Symposium on the Comparative History of Medicine - East and West, August 26-September 3, 1990, Shizuoka, Japan, pp. ix-x)

Cancers or tumors of the MAXILLA or MANDIBLE unspecified. For neoplasms of the maxilla, MAXILLARY NEOPLASMS is available and of the mandible, MANDIBULAR NEOPLASMS is available.

Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms). The majority of intramedullary spinal tumors are primary CNS neoplasms including ASTROCYTOMA; EPENDYMOMA; and LIPOMA. Intramedullary neoplasms are often associated with SYRINGOMYELIA. The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.
