Abstract Background Colorectal cancer is the third most prevailing in whole world. Chemotherapeutic agents which are used for treatment have severe side effects and also unwanted exposure to healthy cells. In present study, polymeric nanoparticles of SN-38 were prepared (using cationic anionic polymers). They optimized by Box Behnken design characterized its physicochemical properties vitro dru...

UNLABELLED We evaluated the clinical utility of positive somatostatin receptor scintigraphy in patients with medullary thyroid cancer (MTC). METHODS Twenty-four MTC patients with increased calcitonin levels underwent somatostatin receptor scintigraphy using 111In-pentetreotide (120-200 MBq) with early (4 hr after injection) and delayed (24 hr) whole-body scans and liver SPECT imaging. In Grou...

Bone scintigraphy or whole-body bone scan is one of the most common diagnostic procedures in nuclear medicine. Since expert physicians evaluate images manually some automated procedure for pathology detection is desired. A robust knowledge based methodology for segmenting body scans into the main skeletal regions is presented. The algorithm is simultaneously applied on anterior and posterior wh...

Objective: To determine the correlation of 18F-FDG SUV value with bone scintigraphy findings, i.e. uptake Tc-99m in diagnosed cases malignancy sclerotic metastasis.
 Study Design: Prospective longitudinal study.
 Place and Duration Study: Armed Forces Institute Radiology Imaging, Rawalpindi Pakistan, from Sep 2020 to Mar 2021.
 Methodology: This study included 30 patients age 18 ...

Introduction: Despite widespread use of 67Gallium for lymphoma evaluation, timing of imaging after injection is a matter of controversy and to the extent of our knowledge no direct comparison has been made between early and delayed gallium images. We aimed to compare 24 and 48 hours post injection planar gallium imaging for evaluation of lymphoma recurrence. Methods: 255 pa...

INTRODUCTION To the best of our knowledge, we present for the first time the bone scintigraphy findings of a patient with Morquio's syndrome. CASE PRESENTATION A 46-year-old Caucasian man with Morquio's syndrome presented with lower back pain six weeks after a left total hip replacement. A whole body bone scan demonstrated an anthropomorphic skeletal pattern consistent with a mucopolysacchari...

This dissertation [4, 2] addresses multi-resolution texture parameterization and proposes an original algorithm ARes for finding more informative resolutions in the sense of classification accuracy. ARes is designed to be used in combination with the existing parameterization algorithm ArTex [3]. The results obtained using the ArTex parameterization algorithm in combination with ARes are compar...

We report the scintigraphic diagnosis of thoracic extramedullary hematopoiesis in a case of alcohol-related macrocytosis. A patient with liver cirrhosis and alcohol-related macrocytosis showed multiple rounded masses in the low thoracic paraspinal region on chest radiography and CT. Whole-body scintigraphy and SPECT imaging of the thorax, after nanocolloid administration, demonstrated expansion...

Cervical spinal Ewing's sarcomas are rare and cause problems in diagnosis. We present an unusual case of a primary extraosseous Ewing's sarcoma arising from the spinal cord. An 18-year-old woman with fever, headache and back pain lasting one month was admitted to the hospital. Whole body bone scintigraphy was performed with 1110 MBq technetium-99m methylenediphosphonate. Scintigraphy clearly sh...
