Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...

mammography remians the procedure of choice in screening asymptomatic women for breast cancer. however, in patients with symptoms, other types of imaging play an important role in the detection of malignancies. the high cost and lack of availability of pet and mri largely precludes the use in this patient population. ti-201 is nbt the imaging agent of choice because of its wash-out and redistri...

basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...

We describe a combination of fabrication techniques and a general process to construct a three-dimensional (3-D) phantom that mimics the size, macroscale structure, microscale surface topology, subsurface microstructure, optical properties, and functional characteristics of a cancerous bladder. The phantom also includes features that are recognizable in white light (i.e., the visual appearance ...

BACKGROUND Advances in Nuclear Medicine physics enabled the specialty of Nuclear Medicine and directed research in other aspects of radiotracer imaging, ultimately leading to Nuclear Medicine's emergence as an important component of current medical practice. DISCUSSION Nuclear Medicine's unique ability to characterize in vivo biology without perturbing it will assure its ongoing role in a pra...

Background: To date, several imaging techniques to track stem cells are used such as positron emission tomography (PET), single photon emission computed tomography (SPECT), Bioluminescence imaging (BLI), fluorescence imaging, CT scan and magnetic resonance imaging (MRI). Although, overall sensitivity of MRI compared to SPECT and Bioluminescence techniques are lower, but due to high spatial reso...
