Coronary CT angiography is widely recognised as a reliable imaging modality for the diagnosis of coronary artery disease. Coronary CT angiography not only provides excellent visualisation of anatomical changes in the coronary artery with high diagnostic value in the detection of lumen stenosis or occlusion, but also offers quantitative characterisation of coronary plaque components. Furthermore...

Background This study aimed to compare the effects of combined endurance-resistance training (CT) versus endurance training (ET) on some cardiovascular markers in patients with heart failure after percutaneous coronary intervention (PCI). Materials and Methods The study applied a randomized, controlled design in which 75 patients with heart failure who had undergone PCI were randomly assigned...

Abdominal aortic aneurysm (AAA) is the most common and critical disease. Bleeding serious complication from a ruptured AAA, which often results in death. Therefore, early diagnosis treatment are only effective means to reduce AAA associated mortality. Positron emission tomography/computed tomography (PET/CT) combines functional anatomical imaging. The expanded application of PET/CT medical fiel...

Magnetic resonance imaging (MRI) provides excellent soft tissue contrast, and in combination with its quantitative functional imaging capability, this modality is ideal for use in radiotherapy. MRI images, either used directly or fused with CT, play an increasingly important role in contouring gross tumor volume (GTV) and organs at risk (OAR) in radiation treatment planning (RTP) systems. The s...

UNLABELLED Pulmonary function tests (PFTs) are routinely used to assess lung function, but they do not provide information about regional pulmonary dysfunction. We aimed to assess correlation of quantitative ventilation-perfusion (V/Q) PET/CT with PFT indices. METHODS Thirty patients underwent V/Q PET/CT and PFT. Respiration-gated images were acquired after inhalation of (68)Ga-carbon nanopar...

In view of the commercial success of integrated PET/CT scanners, there is an increasing interest in comparable SPECT/CT systems. SPECT in combination with CT enables a direct correlation of anatomic information and functional information, resulting in better localization and definition of scintigraphic findings. Besides anatomic referencing, the added value of CT coregistration is based on the ...

Background. Diagnosis of chronic obstructive pulmonary disease (COPD) is confirmed on spirometry but the diagnosis of emphysema remains problematic. The objective of this study was to evaluate the utility of chest radiograph (CXR) and computed tomography (CT) for the diagnosis of emphysema and to correlate these findings with pulmonary function tests (PFTs). Methods. Thirty-five patients with C...

PURPOSE To implement a three-dimensional subtraction functional CT technique to permit rapid quantitative mapping of regional cerebral blood volume (CBV). METHODS The 3-D functional CT technique was implemented in a rabbit model using normal and ischemic animals. Two spiral data acquisitions were performed, one before and one during biphasic administration of contrast material. CBV maps were ...

Objective: To quantitatively aggregate effects of cognitive training (CT) on cognitive and functional outcome measures in patients with traumatic brain injury (TBI) more than 12-months post-injury. Design: We systematically searched six databases for non-randomized and randomized controlled trials of CT in TBI patients at least 12-months post-injury reporting cognitive and/or functional outcome...

Neuroimaging has evolved from Computed Tomography (CT), CT-Positron Emission Tomography (CT-PET) and Magnetic Resonance Imaging (MRI) scanner in 1970s and 1980s to functional MRI (fMRI), Diffusion Tensor Imaging (DTI) and Magnetic Source Imaging (MSI) or Magnetoencephalography-MRI (MEG-MRI) fusion in 1990s and 2000s. Anatomical and functional neuroimages are currently regarded by most as vital ...
