OBJECTIVE The goal was to determine whether computed tomographic (CT) scans led to better acute care of young children with headache presenting the emergency department (ED). METHODS We examined the records of 364 children 2 to 5 years of age who presented with headache to a large urban ED between July 1, 2003, and June 30, 2006. By reviewing initial history and examination findings, we first...

BACKGROUND Diagnostic imaging is essential to assess the lame patient; lesions of the elbow joint have traditionally been evaluated radiographically, however computed tomography (CT) has been suggested as a useful technique to diagnose various elbow pathologies. The primary objective of this study was to determine the sensitivity and specificity of CT to assess medial coronoid disease (MCD), us...

Introduction. Computed tomography (CT) has many diagnostic advantages, spurring growth in the number of CT examinations. As the use of CT increases, the potential for radiation-induced adverse effects has become an issue. The primary objective of this study was to assess the liberal use of CT induced radiation exposure in patients with multiple blunt traumas. The secondary objective was to inve...

Objectives This retrospective study evaluated whether the use of additional anterior 99mTc-sestamibi/123I pinhole imaging improves the outcome of 99mTc-sestamibi/123I subtraction SPECT/CT in parathyroid scintigraphy (PS). Materials and Methods PS using simultaneous dual-isotope subtraction methods and an acquisition protocol combining SPECT/CT and planar pinhole imaging was performed for 175 ...

Lignins, along with condensed tannins (CTs) and salicylate-derived phenolic glycosides, constitute potentially large phenylpropanoid carbon sinks in tissues of quaking aspen (Populus tremuloides Michx.). Metabolic commitment to each of these sinks varies during development and adaptation, and depends on L-phenylalanine ammonia-lyase (PAL), an enzyme catalyzing the deamination of L-phenylalanine...

Coiled tubing (CT) is widely used in drilling, workover, completion, fracturing and stimulation the field of oil gas exploration development. During CT operation, will present a gas–liquid two-phase flow state. The prediction frictional pressure drop for fluid tube an important part hydraulic design, its accuracy directly affects success technique. In this study, we analyzed effects void fracti...

Computed tomography (CT), the standard method to assess tumor response to cetuximab in incurable squamous cell carcinoma of the head and neck (SCCHN), performs poorly as judged by the disparity between high disease control rate (46%) and short time to progression (TTP) (70 days). F-18 fluorodeoxyglucose positron emission tomography (FDG-PET)/CT is an alternative method to assess tumor response....

INTRODUCTION Correct target positioning is crucial for accurate dose delivery in breast radiotherapy resulting in utilisation of daily imaging. However, the radiation dose from daily imaging is associated with increased probability of secondary induced cancer. The aim of this study was to quantify doses associated with three imaging modalities and investigate the correlation of dose and varying...

Thirty patients with chiasma syndrome attributed to ischemic processes of various origins are described. The initial diagnosis was made after an investigation based on polytome pneumoencephalography and angiography. This diagnosis was confirmed later with the use of high-resolution computed tomography (CT) and refined angiographic techniques. The ischemic chiasma syndrome may be classified into...

Source of Funding: Self Conflicts of interest: None DOI: 10.16965/ijims.2016.126 Renal replacement lipomatosis is a rare benign entity, characterized by diffuse replacement of renal parenchyma, sinus and hilum with adipose tissue resulting in renal parenchymal atrophy. Etiology may be secondary to obesity, cushing’s syndrome, corticosteroid excess or idiopathic. Renal replacement lipomatosis is...
