Early finding and analysis of brain tumor are essential to enhance the surgical planning and thus extend the survival of patients. Medical imaging techniques (MIT’s) are useful to view the internal structure of the brain which makes the medical professional to diagnose abnormal conditions and guide therapeutic procedures. Few MIT’s are handling in the medical industry to identify the brain tumor and each technique has different risks and benefits. The concerning techniques are single photon emission computed tomography (SPECT), computed tomography (CT), positron emission tomography (PET), magnetic resonance imaging (MRI), functional MRI (fMRI), and blood oxygen level dependent (BOLD). This paper presents the importance of MIT’s in brain tumor treatment.

Neuroimaging is traditionally divided into structural and functional imaging. Structural imaging looks at brain structure or anatomy and includes computed tomography (CT) and magnetic resonance imaging (MRI). Functional techniques seek to examine the physiological functioning of the brain, either at rest or during activation, and include single photon emission computed tomography (SPECT), positron emission tomography (PET), MRI spectroscopy, functional MRI (fMRI) and encephalographic brain mapping. Although fMRI, MRI spectroscopy and brain mapping are likely to have clinical applications in the near future, the main imaging modalities of current clinical relevance to psychiatrists are CT, MRI and SPECT, which will be the focus of this article.

The imaging techniques of magnetoencephalography (MEG), computed tomography (CT), positron emission tomography (PET) and single photon emission computed tomography (SPECT) are reviewed, and the analytical solutions of the relevant inverse problems are presented. The numerical implementation of the exact formulas yield accurate reconstructions for both realistic phantoms as well as real data.

Cyclodextrins (CDs) are naturally occurring cyclic oligosaccharides consisting of multiple glucose subunits. CDs are widely used in host–guest chemistry and biochemistry due to their structural advantages, biocompatibility, and ability to form inclusion complexes. Recently, CDs have become of high interest in the field of medical imaging as a potential scaffold for the development of a large variety of the contrast agents suitable for magnetic resonance imaging, ultrasound imaging, photoacoustic imaging, positron emission tomography, single photon emission computed tomography, and computed tomography. The aim of this review is to summarize and highlight the achievements in the field of cyclodextrin-based contrast agents for medical imaging.

Abstract One of the most significant causes of heart failure is coronary heart disease and subsequent left ventricular dysfunction. The prognosis and perioperative mortality are influenced by left ventricular function, which is also an important predictor marker following revascularization. The evaluation of myocardial perfusion is of utmost importance in patients who present several symptoms before choosing cardiac catheterization as treatment. The evaluation of myocardial perfusion and myocardial viability leads to superior diagnostic and treatment algorithms, thus resulting in an important improvement in the outcomes of patients with coronary artery disease. Color Doppler myocardial imaging, single-photon emission computed tomography (SPECT), contrast perfusion echocardiography, positron emission computed tomography (PET) and magnetic resonance imaging (MRI) are currently used methods for assessing myocardial perfusion. This review aims to summarize the benefits and disadvantages of each of these techniques.
