The main goal of the article is to compare the effective radiation doses received by the leading interventional cardiologist during the angiographic procedures. A comparison is done between the dose load during three procedures—LAD-stenting, LCx-stenting and RCA-stenting. An angiographic X-ray system Philips Allura Xper FD10 (with G-arm) was used for this study. The dose obtained was measured with an X-ray-Gamma Dosimeter 27091. The dose measurements were made for the respective projections of e...

This article is a continuation of the study of the dose load received by an interventional cardiologist during angiographic procedures and particularly during RCA stenting. To calculate the dose load, dosimetric measurements of the effective dose were carried out while working with a Philips Allura Xper FD10 angiographic system in the invasive department of the Special Hospital for Active Treatment in Cardiology, Varna, Bulgaria. The measurements were carried out for the two operating modes of t...

The study of the dose load received by the personnel working with x-ray equipment is a very important task in the modern world. The purpose of this article is to assess the dose load based on published dosimetric measurements obtained by an interventional cardiologist from scattered X-ray during the angiographic procedure LCx stenting. The procedure is carried out under X-ray guidance using a Philips Allura Xper FD10 system. The dose calculations and assessments are made for three positions of t...

Based on published dosimetric measurements, the dose load received by the interventional cardiologist from scattered X-ray radiation was assessed for an angiographic LAD stenting procedure under X-ray guidance. An angiographic X-ray system “Philips Allura Xper FD10” was used for the study. The dose assessment calculations were made for three positions of the patient table—basic, lowest and highest—and for three measurement points—“head”, “gonads” and “feet”, in which the received dose was measur...

Ascaris lumbricoides is the most common helminth affecting humans. It is endemic in tropical and underdeveloped countries. It particularly infects children but most often is asymptomatic. Sometimes, it can mimic a surgical abdominal emergency. When it is suspected, its diagnosis is made on the parasitological examination of stool. We here report the case of a diagnosis of intestinal ascariasis made on ultrasound in an 8-year-old child who consulted for an acute abdominal syndrome which initially...

CT technology has been widely used in various fields such as medical treatment, industry, and materials. Recently years, cone-beam CT (CBCT) used in the medical field is replacing the traditional spiral CT slowly due to its unique advantages. Improving the performance of CBCT and the image reconstruction algorithms could obtain higher quality of images, meanwhile, these also reduce the exposure time of X-ray irradiation. And image reconstruction techniques based on sparse angles have benefits fo...

Cavernous hemangiomas are a benign lesion that can affect any parth of the neurax. However, pure lumbar extradural localization is not common. Their ethiopatogenesis is uncertain and still debated but actually, they are considered as congenital vascular malformations. The clinical presentation is not specific, they can simulate any expansive process of the epidural space which makes the condition difficult to the preoperative diagnosis. Although unusual and in ...

Arachnoid cyst of petrous apex is an uncommon cyst lesion that herniates from the posterolateral portion of the Meckel’s cave into the petrous apex. It can be unilateral or bilateral, usually observed in female population. Its etiopathogenesis is still uncertain and many theories were reported in the literature. The characteristic imaging appearance, topography and benign behavior of the lesion allow to differentiate arachnoid cys ...

Pseudo papillary and solid pancreatic tumor (PPSPT) is a rare tumor that occurs almost exclusively in adolescents and young women. Radiological ex-ploration is mainly based on ultrasound and CT, which can often guide the diagnosis. We report the case of a 12-year-old girl, who was referred for suspicion of a hydatid cyst of the liver. Abdominal ultrasound showed a large solid-cystic mass, in contact with the hepatic hilum. Abdomin ...

Langerhans cells histiocytosis (LCH) is a disease caused by the proliferation and abnormal accumulation of Langerhans cells in different tissues and organs. It is a rare disease that still hides many of its mysteries as to its etiology and pathophysiology. The cerebral localization remains exceptional and dominated by hypothalamic-pituitary axis involvement. We report a case of a 20-year-old patient followed for acquired central d ...
