Lowering the Dose in Head CT Using Adaptive Statistical Iterative Reconstruction
TLDR
The effect of ASIR on noise reduction observed in the present study of head CT is less than that reported previously in abdomen and chest CT, and these findings encourage further prospective studies in larger patient samples. Expand
Transluminal balloon dilatation of the lacrimal drainage system for the treatment of epiphora.
TLDR
Evaluation of transluminal balloon dilatation done under digital subtraction fluoroscopic monitoring in the treatment of incomplete and complete obstruction of the lacrimal drainage system in patients with epiphora shows that the procedure has a high failure and recurrence rate when the obstruction is complete. Expand
Bilateral persistence of type 1 proatlantal arteries: report of a case and review of the literature.
TLDR
A case with bilateral persistent proatlantal arteries that arose from internal carotid arteries, entered the skull via the foramen magnum and united with the horizontal portions of vertebral arteries is presented. Expand
Percutaneous management of bile duct stones.
TLDR
Interventional stone removal techniques mainly include extraction through the T-tube tract with baskets or forceps and expulsion into the duodenum by means of baskets or balloon catheters with the dilatation of the sphincter of Oddi. Expand
Computed tomographic evaluation of surgically significant vascular variations related with the temporal bone.
TLDR
To aid diagnosis, treatment planning and surgery, CT scanning is currently a very reliable tool in determining these conditions and special attention should be paid to the position of the vascular structures in the preoperative temporal bone CT scans. Expand
Unfused or twig-like middle cerebral artery.
TLDR
The aim is to define and evaluate the angiographical features of Uf/Tw MCA, a rare unfused or twig-like MCA variation that may cause mis diagnosis and unnecessary treatment attempts. Expand
Interventional radiology in the lacrimal drainage system.
TLDR
Balloon dacryocystoplasty and nasolacrimal polyurethane stent placement are the main fluoroscopically guided interventions for the treatment of epiphora by recanalizing the obstructed LDS. Expand
Lens of the eye: radiation dose in balloon dacryocystoplasty.
TLDR
The lens of the untreated eye receives a higher dose than that of the treated eye because of its closer proximity to the x-ray tube in a lateral projection, and even the highest measured radiation dose still was well below the deterministic threshold for lens opacity and cataract formation. Expand
Endovascular treatment of peripheral vascular lesions with stent-grafts.
TLDR
The results suggest that endovascular treatment of various types of peripheral vascular lesions with stent-grafts is a low-risk procedure, which appears to be less invasive than surgery. Expand
Treatment of autonomous thyroid nodules: safety and efficacy of sonographically guided percutaneous injection of ethanol.
TLDR
The results show that sonographically guided percutaneous injection of ethanol can be used as an alternative treatment of autonomous thyroid nodules with the aim of eliminating the possible risk factors of surgery and radioiodine. Expand
