Precision Radiotherapy: 18F-FDG PET-based radiotherapy planning in Head and Neck cancers
Published in World Journal of Nuclear Medicine
Precision medicine is gaining importance in this era of molecular imaging where the molecular features of a disease can be noninvasively assessed and treated with personalized medicine. This is especially suited for head and neck cancers (HNCa). Early stage HNCa are ideally managed with radiotherapy (RT) or surgery. Head and neck (HN) is a complex ...
Attenuation correction in single-photon emission computed tomography for NURBS-based cardiac-torso phantom using dual-en...
Published in World Journal of Nuclear Medicine
Single photon emission tomography is widely used to detect photons emitted from the patient. Some of these emitted photons suffer from scattering and absorption because of the attenuation occurred through their path in patient's body. Therefore, the attenuation is the most important problem in single-photon emission computed tomography (SPECT) imag...
Diffuse pleural metastases of osteosarcoma detected by bone scan
Published in World Journal of Nuclear Medicine
Osteosarcoma (OS) is a fast-growing tumor, with a high risk of local recurrence and distant metastases, with the lung and bone being the most common sites of dissemination occurring in approximately 80% of cases. Pleural metastases rarely occurs and the appearance of diffuse pleural thickening with ossification is not usual, with few such cases rep...
Evaluation of estrogen expression of breast cancer using 18F-FES PET CT-A novel technique
Published in World Journal of Nuclear Medicine
Estrogen receptor (ER) expression in breast cancer is routinely studied on immunohistochemistry (IHC) of tissue obtained from core biopsy or surgical specimen. Sampling error and heterogeneity of tumor may incorrectly label a breast tumor as ER negative, thus denying patient hormonal treatment. Molecular functional ER imaging can assess the in-vivo...
Precise localization of biliary leak post laparoscopic cholecystectomy with hepatobiliary scintigraphy and adjunct singl...
Published in World Journal of Nuclear Medicine
Laparoscopic cholecystectomy is commonly performed as the treatment of choice for symptomatic gallstone diseases. Bile leak is a potential complication of this procedure and the cystic duct stump is the most common site of leakage. Early diagnosis and treatment of bile leak is crucial in decreasing the morbidity and mortality related to this compli...
An overview on prostate-specific membrane antigen uptake in malignancies other than prostate cancer: A pictorial essay
Published in World Journal of Nuclear Medicine
Prostate-specific membrane antigen (PSMA) is a Type II transmembrane glycoprotein which is extremely overexpressed in prostate cancer epithelial cells. Recently, PSMA-targeted small molecule labeled with 68Ga and 99mTc allowed precise molecular imaging of prostate cancer and PSMA-targeted small molecule labeled with 177Lu leads to the development o...
Improving technetium-99m methylene diphosphonate bone scan images using histogram specification technique
Published in World Journal of Nuclear Medicine
In this study, we have proposed and validated that histogram of a good-quality bone scan image can enhance a poor-quality bone scan image. The histograms of two good-quality technetium-99m methyl diphosphonate bone scan images IA and IB recommended by nuclear medicine physicians (NMPs) were used to enhance 87 poor-quality bone scan images. Processe...
Primary pancreatic lymphoma camouflaged under the umbrella of spectrum of neuroendocrine tumors in somatostatin receptor...
Published in World Journal of Nuclear Medicine
Primary pancreatic lymphomas are very rare as compared to other pancreatic neoplasms. However, unlike carcinomas, pancreatic lymphoma is treatable with satisfactory cure rates. Somatostatin receptor (SSTR) positron emission tomography/computed tomography (PET/CT) with 68Ga-DOTANOC is a well-established diagnostic modality in the management of neuro...
Isolated aplasia of submandibular salivary gland and contralateral prominence of submandibular and sublingual salivary g...
Published in World Journal of Nuclear Medicine
Prostate-specific membrane antigen (PSMA)-targeted imaging is now an effective tool for the evaluation of prostate cancer patients. Although salivary glands take up 68Ga-PSMA avidly, pathologies of these glands may be readily noticeable. Herein, we present a case of prostate cancer referred for 68Ga-PSMA positron emission tomography–computed tomogr...
