Experience with Echo-Encephalography and Ultrasonic Lung Scans

Isotope Encephalography: Experience with 100 Cases.

Isotopes have been used for the detection and location of intracranial lesions since 1948 (Moore, 1948). In 1947 Moore demonstrated that fluorescein injected intravenously was selectively absorbed by gliomas (astrocytomas) and other tumours. When an ultraviolet light was shone on the exposed brain, a glioma reaching the surface reflected a different colour-yellow -from the remainder of the brai...

Experiences with RIHSA encephalography.

CONVENTIONAL neuroradiological techniques allow accurate location and fairly accurate identification of intracranial masses. Unfortunately, these procedures necessitate admission to hospital, cause some discomfort, and are not free from danger. Moreover, carotid angiography cannot reliably demonstrate lesions situated posteriorly in the hemispheres and, as it relies mainly on the detection of d...

Improved spectroscopic imaging using echo-planar scans and sparse reconstruction

INTRODUCTION Model-based spectroscopic imaging techniques were originally proposed to reduce the number of phase encodes, and consequently the scan time [1,2]. However, in practice, these techniques can give significant artifacts for a low number of spatial encodes. This is mainly due to the assumptions embedded in the model being violated. On the other hand, it is well known that fast scan tec...

Thyroidectomy with ultrasonic dissector: a multicentric experience.

INTRODUCTION We have conducted a clinical controlled trial (CCT) on patients who had undergone thyroidectomy for goitre or thyroid carcinoma. The endpoint of this study was to evaluate the benefits of ultrasonic dissector vs conventional technique (vessel ligation and tight) in patients undergoing thyroid surgery. PATIENT AND METHODS Between January 2007 and December 2009 a CCT was conducted ...
