Optimizing Performance Parameters of ChemicallyDerived GraphenepSi Heterojunction Solar panel

Significant 68Ga-PSMA-11 activity is commonly observed in the lacrimal and salivary glands on PSMA PET/CT. An 80-year-old man after radical prostatectomy was evaluated with 68Ga-PSMA-11 PET/CT. There was no obvious PSMA uptake in the bilateral lacrimal, parotid, and submandibular glands. Subsequently, based on laboratory examination results and 99mTcO4 salivary gland scintigraphy, this patient was diagnosed with Sjögren syndrome, which accounted for the absence of uptake by the glands. This case showed the potential of 68Ga-PSMA-11 PET/CT in the evaluation of the lacrimal glands and major salivary glands.

A 55-year-old man with cough, bone pain, and cervical lymphadenopathy underwent both 18F-FDG and 18F-PSMA-1007 PET/CT scans with clinical suspicion of malignant disease. Compared with 18F-FDG PET/CT, 18F-PSMA PET/CT showed intense tracer uptake in the prostate gland, lungs, osteogenic lesions, and multiple lymph nodes. Interestingly, we also found the high tracer concentration of pulmonary lymphangitic carcinomatosis, a very rare form of prostate cancer metastasis to the lung, on 18F-PSMA-1007 PET/CT images.

Because prostate-specific membrane antigen (PSMA) expression is universal in juvenile nasal angiofibroma (JNA), PSMA PET/CT is commonly used in the postoperative setting using the postoperative angiofibroma radionuclide imaging study protocol. Our study aims to illustrate physiological PSMA ligand uptake distribution characteristics in the salivary glands, specifically the tubarial glands with tumor, to aid in accurate PSMA PET/CT analysis.
Forty-three consecutive patients who underwent a dedicated head and neck spot PSMA PET/CT for JNA were evaluated retrospectively. PSMA SUVmax values in the tumor, tubarial, parotid, submandibular, and sublingual salivary glands were determined visually and quantitatively.
All the tumors and the salivary glands showed increased tracer uptake. The median SUVmax ± SD ratios of the tumor, right and left tubarial gland, right and left parotid gland, right and left submandibular gland, and right and left sublingual gland were 2.7 ± 0.8 (range, 0.5-7.5), 3.8 ± 1.9 (range, 0nd care must be given during the planning of stereotactic radiotherapy for JNAs.
A 73-year-old man experienced chest tightness and shortness of breath for 9 months. Chest CT revealed a large right upper lobe mass. Pathology from CT-guided biopsy demonstrated poorly differentiated adenocarcinoma of the lung. Whole-body bone scan was acquired to evaluate possible bone metastasis. However, he was injected with 99mTcO4- erroneously instead of 99mTc-MDP. The images showed a focus of elevated activity of 99mTcO4- in the known lung lesion.

We report the case of a 21-year-old man referred to our institution for the initial staging of an osteoblastic osteosarcoma of the right femur. An 18F-NaF PET/CT demonstrated millimetric pleuroparenchymal metastases, later confirmed on follow-up. These lesions were not reported on both dedicated chest CT and 18F-FDG PET/CT.

Herpes zoster infection caused by reactivation of dormant varicella zoster virus results in painful vesicular rash in corresponding dermatome. We report a case of a 56-year-old woman with breast cancer who was referred to PET/CT scan for adjuvant chemotherapy response assessment. Her scan showed multiple FDG-avid skin lesions. Blinded to the patient's clinical information, these skin lesions initially looked suspicious for soft tissue metastases. However, the patient history revealed that she had been experiencing herpes zoster infection during the scan, and these lesions with FDG uptake were eventually confirmed to be caused by herpes zoster infection by physical examination.
