conclusion the designed split-bolus mdct technique can be proposed alternatively to triphasic mdct and in a single-pass to pvp in the initial staging and in the follow-up respectively in oncologic patients. patients and methods we retrospectively analyzed the follow-up split-bolus 64-detector row ct protocol in 36 oncologic patients to characterize focal liver lesions. the split-bolus mdct prot...
AIM To assess the diagnostic accuracy and radiation dose of split-bolus multidetector-row computed tomography (MDCT) protocol in the detection and characterization of focal liver lesions in oncologic patients. PATIENTS AND METHODS We retrospectively analyzed triphasic CT at initial diagnosis and follow-up split-bolus 64-detector row CT protocol in 48 oncologic patients with focal liver lesion...
Background: Chest CT is a commonly used examination for the diagnosis of lung diseases, but a breast within the scanned field is nearly never the organ of interest.Objective: The purpose of this study is to compare the female breast and lung doses using split and standard protocols in chest CT scanning.Materials and Methods: The sliced chest and breast female phantoms were used. CT exams were p...
In this paper, we present a novel attack tree paradigm called attack countermeasure tree (ACT) comprising an additional attack resistant element known as the Split-protocol. ACT which circumvent the fabrication and way out of a state-space representation and takes keen on account attack, as well as countermesures (in the form of detection and mitigation events). Split-protocol as an attack resi...
BACKGROUND The aim of this study was to investigate the feasibility of a split-bolus combined phase contrast-enhanced computed tomography protocol in evaluation of liver vasculature in hepatocellular carcinoma (HCC) patients for the purpose of surgery guidance. MATERIAL AND METHODS Two groups of patients were recruited for the study: 24 consecutive cases of HCC who underwent multiphasic CT exam...
Distributed Denials of Service (DDoS) attacks have become the daunting problem for businesses, state administrator and computer system users. Prevention and detection of a DDoS attack is a major research topic for researchers throughout the world. As new remedies are developed to prevent or mitigate DDoS attacks, invaders are continually evolving new methods to circumvent these new procedures. ...
BACKGROUND In oncologic patients, the liver is the most common target for metastases. An accurate detection and characterization of focal liver lesions in patients with known primary extrahepatic malignancy are essential to define management and prognosis. OBJECTIVES To assess the diagnostic accuracy of the split-bolus multidetector-row computed tomography (MDCT) protocol in the characterizat...
در سال 1989 پوپوف مهاربند موسوم به مهاربند split-xواگرا که از نو مهاربندهایebf می باشد را پیشنهاد داد. مهاربند split-x واگرا هنوز به طور رسمی در آیین نامه ها شناخته نشده و درزمینه عملکرد و پاسخ لرزه ای این مهاربند در برابر شتاب نگاشت های واقعی زلزله تحقیقی جامع بر اساس تحلیل های دقیق دینامیکی غیرخطی صورت نگرفته است. یکی از مهم ترین پارامترهای لرزه ای سازه ها در برابر نیروهای زلزله، ضریب رفتار م...
