ConclusionThis phase 0 exploratory IND study shows that nanocarrier188Re-liposome achieves favorable tumor accumulation and tumor to normal organ uptake ratios for a subset of cancer patients. The clinical pharmacokinetic, biodistribution, and dosimetry results justify a further dose-escalating phase 1 clinical trial.Trial registrationTaiwan FDA MA1101G0 (Jan 31, 2012).

Conclusion Radioguided pulmonary nodule localization is a reliable procedure with a high rate of success, minimal complications, and lower risk of failures, with no associated mortality or significant morbidity. Our SPECT/CT system is the first to benefit from the technological improvement with successfully implementation and application of fluoroscopy to SPECT/CT.

Conclusion NP-59 adrenal scintigraphy is a useful imaging test to detect APA. Lateralization by this modality prior to surgical intervention may reduce the need for such invasive procedures as adrenal venous sampling.

Objective Following the implementation of single-photon emission computed tomography ventilation/perfusion (SPECT V/Q) in our department, we previously carried out an observational study over the period 2011–2013 that showed the safety of SPECT V/Q to rule out pulmonary embolism (PE). However, PE prevalence (28%) was high compared with some studies. Our hypothesis was that the use of SPECT V/Q may be responsible for an overdiagnosis of PE, especially at the implementation phase of the test. The aim was to carry out a time trend analysis of the evolution over the years of PE diagnosis with SPECT V/Q. Patients and m...

AbstractPurpose of ReviewRadionuclide myocardial perfusion imaging (MPI) continues to be the most reliable modality for diagnosis of hemodynamically significant coronary artery disease (CAD). The application of radionuclide MPI using single photon emission computed tomography (SEPCT) and positron emission tomography (PET) for CAD is reviewed, with emphasis on diagnosis and risk stratification.Recent FindingsContemporary studies have reported the diagnostic and prognostic value of novel imaging protocols, employing stress-first or stress-only approach. In addition, the superior diagnostic value of PET has been established w...

AbstractObjectiveTo compare the detection rate of Tc-99m dimercaptosuccinic acid (DMSA) renal single photon emission computerized tomography (SPECT) with that of planar scan for renal cortical defects in infants under one year of age with suspected acute pyelonephritis.MethodsSixty infants under one year of age who exhibited fever and pyuria were prospectively included in this study. All infants underwent concurrent Tc-99m DMSA renal planar scan and SPECT. Detection rates for cortical defects and the numbers of cortical defects in both kidneys were compared between Tc-99m DMSA planar scan and SPECT. The cortical defects we...

Aim Combined 68Ga-PSMA-617 PET imaging and 177Lu-PSMA-617 therapy is a precise targeted theranostic approach for patients with metastatic castration-resistant prostate cancer (mCRPC). The purpose of this study was to determine whether pretherapeutic standard uptake value (SUV) in 68Ga-PSMA-617 PET could indicate the effective dose in the main organs and absorbed dose in tumor lesions. Methods After institutional review board approval and informed consent, 9 patients with mCRPC were recruited and underwent 68Ga-PSMA-617 PET/CT scans. Five patients received 177Lu-PSMA-617 (1.30–1.42 GBq, 35–38.4 mCi) and the...

A 40-year-old man with biopsy-proven papillary thyroid cancer received 131I radiotherapy. Posttherapy scan showed not only multiple foci of intense activity in the neck but also a small focal activity in the region of right upper mediastinum, confirmed by SPECT/CT images. This activity was suspected as mediastinal lymph node metastasis. However, pathology examination after the resection showed thymic cyst.

Publication date: Available online 11 May 2019Source: SeizureAuthor(s): Csaba Juhász, Flóra JohnAbstractChildren with epilepsy and normal structural MRI pose a particular challenge in localization of epileptic foci for surgical resection. Many of these patients have subtle structural lesions such as mild cortical dysplasia that can be missed by conventional MRI but may become detectable by optimized and advanced MRI acquisitions and post-processing. Specificity of objective analytic techniques such as voxel-based morphometry remains an issue. Combination of MRI with functional imaging approaches can improve t...

Conclusion99mTc-HYNIC-IL-2 scintigraphy proved to be a good technique to detect grade 2 and 3 acute rejection in a small sample population of patients after lung transplantation. Larger studies are necessary to really show the added value of this non-invasive specific imaging technique over transbronchial biopsy. Alternatively, imaging with the PET tracer18F-IL-2 may be useful for this purpose.
