Transit Time Measurement in Indicator Dilution Curves: Overcoming the Missing Ground Truth and Quantifying the Error

Frontiers in Physiology, 2021
The vascular function of a vessel can be qualitatively and intraoperatively checked by recording the blood dynamics inside the vessel via fluorescence angiography (FA).

Transurethral resection and surveillance of bladder cancer supported by 5-aminolevulinic acid-induced fluorescence endoscopy [PDF]

, 1999
Purpose: We determined whether neoplastic disease, which was missed under white light can be found during transurethral resection of bladder cancer by 5-aminolevulinic acid-induced porphyrin fluorescence.

Comparison of Optical Imaging Techniques to Quantitatively Assess the Perfusion of the Gastric Conduit during Oesophagectomy

Applied Sciences, 2020
In this study, four optical techniques—Optical Coherence Tomography, Sidestream Darkfield Microscopy, Laser Speckle Contrast Imaging, and Fluorescence Angiography (FA)—were compared on performing an intraoperative quantitative perfusion assessment of the

Fluorescence angiography of the iris. [PDF]

British Journal of Ophthalmology, 1970
Jensen and Lundbaek (i 968) reported a technique of fluorescence iris angiography using a lens of 20 cm. focal length placed in front of the Zeiss fundus camera. This technique, though attractive in its simplicity, has certain disadvantages, i.e. the image size of 24 X 24 mm. and distortion at the margins of the image.

Indocyanine green fluorescence angiography decreases the risk of anastomotic leakage after rectal cancer surgery: a systematic review and meta-analysis

Frontiers in Medicine, 2023
BackgroundAnastomotic leakage is a serious complication after rectal cancer resection. Intraoperative use of indocyanine green fluorescence angiography (ICGFA) can help prevent anastomotic leakage, but its use is controversial.

Comparing laser speckle contrast imaging and indocyanine green angiography for assessment of parathyroid perfusion

Scientific Reports, 2023
Accurate intraoperative assessment of parathyroid blood flow is crucial to preserve function postoperatively. Indocyanine green (ICG) angiography has been successfully employed, however its conventional application has limitations.

Indocyanine Green Angiography for Continuously Monitoring Blood Flow Changes and Predicting Perfusion of Deep Inferior Epigastric Perforator Flap in Rats

Journal of Investigative Surgery, 2021
Background Deep inferior epigastric perforator (DIEP) flap approach has excellent outcomes and low morbidity. However, it is associated with high rates of perfusion-related complications.

Inequity of access to investigation and effect on clinical outcomes: prognostic study of coronary angiography for suspected stable angina pectoris [PDF]

, 2008
Objectives: To determine whether coronary angiography for suspected stable angina pectoris is underused in older patients, women, south Asian patients, and those from socioeconomically deprived areas, and, if it is, whether this is associated with higher
