F-FDG PET/CT Imaging of Pulmonary Mucinous Cystadenocarcinoma with Signet Ring Cells.

A 63-year-old male with a recently diagnosed right lung lesion was referred for staging. F-FDG PET/CT scan revealed a hypodense, cystic-like mass in the right upper lung lobe, which demonstrated low, diffuse F-FDG uptake, likely due to the presence of mucus, as well as intensely hypermetabolic right hilar and right paratracheal lymph nodes. Transbronchial biopsy revealed a primary pulmonary mucinous cystadenocarcinoma with the presence of signet ring cell carcinoma, a co-existence of two rare variants of lung adenocarcinoma.

68Ga DOTATATE PET/CT uptake in spinal lesions and MRI correlation on a patient with neuroendocrine tumor: potential pitfalls.

A 62-year-old female patient with suspected insulinoma underwent 68Ga DOTA-TATE PET/CT for characterization and staging. This demonstrated a focus of uptake in the pancreas and 3 foci of uptake in the spine. An MRI of the spine performed to further characterize the lesions revealed the presence of a meningioma and degenerative changes, both of which showed 68Ga DOTA-TATE uptake.

Hybrid cardiac imaging: insights in the dilemma of the appropriate clinical management of patients with suspected coronary artery disease.

Aim: To evaluate the potential of SPECT myocardial perfusion imaging (MPI)-computed tomography coronary angiography (CTCA) hybrid fusion imaging to improve the diagnostic performance of cardiac SPECT/MPI and CTCA alone in order to act as more accurate gate keeper to further investigation invasive or not.

Methods And Results: Twenty-five patients were subjected to SPECT/MPI and CTCA within a period of 1 month without any medical treatment modification. A fusion software package was used for cardiac SPECT-CTCA image fusion.

Alterations of global gastrointestinal motility after sleeve gastrectomy: a prospective study.

Objectives: To evaluate the role of sleeve gastrectomy (SG) in gastrointestinal motility.

Background: SG is a widely used bariatric operation leading to weight loss and early improvement of patient's metabolic profile. Current data indicate faster postoperative gastric emptying, but detailed studies on alterations in small bowel motility are missing.
