Therapeutic response and safety of radioligand therapy with Lu-PSMA-617 in metastatic castration-resistant prostate cancer patients.

Prostate cancer is one of the most common cancers and leading cause of death due to cancer across the globe. This persuaded researchers to devise innovative treatment modalities that may prove effective, safe, and demonstrate better outcomes in terms of patient morbidity and survival. The advancement in theranostics such as lutetium-177 (Lu)-PSMA-617 radioligand therapies can target prostate cancer cells causing negligible or no damage to most of the normal tissues in patients.

SUV max as Predictor of Metastatic Disease on 18 F-FDG PET-CT in Hepatocellular Carcinoma.

Objective: To ascertain the utility of maximum standardised uptake value (SUVmax) in 18F-FDG PET-CT in predicting metastatic disease burden in hepatocellular carcinoma (HCC) patients.

Study Design: Descriptive study. Place and Duration of the Study: Department of Nuclear Medicine and PET-CT Imaging, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, Pakistan, from April to October 2022.

Detection of Primary Hepatocellular Carcinoma on F-Fluorodeoxyglucose Positron Emission Tomography-computed Tomography.

Aims And Background: Hepatocellular carcinoma (HCC), ranks as the third most prevalent malignancy contributing to cancer-related death on a global scale. Hepatocellular carcinoma is known to be the fifth most frequently diagnosed malignancy of the males while among females, it is ranked as the seventh most common malignancy. The study was conducted to detect the sensitivity of primary HCC using F-flourodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan.

Gallbladder Emulating Hepatic Haemangioma On Gastrointestinal Bleed Scan.

Tc-99m labelled erythrocyte scan is a sensitive method for detection of gastrointestinal (GI) bleed and liver haemangioma but false positive results can occur, as in this case gallbladder is visualized which is not a common finding. Single‑photon emission computed tomography/computed tomography (SPECT-CT) is helpful to avoid such false‑positive results.

Ga-PSMA PET-CT and PSMA score affecting therapeutic decision-making in high-risk prostatic carcinoma.

Purpose: This research study was conducted to evaluate the impact of (Ga)-tagged prostatic-specific membrane antigen (Ga-PSMA) positron emission tomography and computed tomography (PET-CT), compare its role with conventional radiology in early staging of high-risk prostate cancer, and calculate the PSMA score evaluating its usefulness in Ga-PSMA PET-CT reporting in our patient population.

Material And Methods: Ga-PSMA PET-CT of 65 high-risk cases of prostate cancer was performed for staging purpo-ses. Any change in disease stage was noted after Ga-PSMA PET-CT findings and PSMA score leading to a change in the management plan.

Comparing High and Low-Dose Radio-Iodine Therapy in Thyroid Remnant Ablation Among Intermediate and Low-Risk Papillary Thyroid Carcinoma Patients-Single Centre Experience.

The role of Iodine-131 therapy is well established as an adjuvant therapy and for thyroid remnant ablation in differentiated thyroid cancer (DTC); however controversy still exists regarding its appropriate dose. Purpose of this study was to compare the effectiveness of low-dose and high-dose Iodine-131 ablation therapies in low- and intermediate-risk PTC patients. Eighty-four patients were divided equally into Group I: Ablated with high dose of Iodine-131 and Group II: Ablated with low dose of Iodine-131.

Tc-99m PSMA and Lu-177 PSMA Theranostic Pair in a Patient of Metastatic Castration Resistant Prostate Cancer.

Prostate specific membrane antigen (PSMA) targeted PET-CT imaging labeled with Gallium-68 (68Ga) is a standard diagnostic investigation in patients of carcinoma of prostate, for detection of primary tumour, initial staging of high risk disease for metastases as well as detection of recurrence. 99mTechnetium labeled PSMA SPECT-CT is a more cost-effective and logistically simple alternative for it. We present pre-therapy images of 99mTc-PSMA and post-therapy scan with 177Lu- PSMA in the same patient.

Highly active Ce, Y, La-modified Cu/SiO catalysts for hydrogenation of methyl acetate to ethanol.

Rare earth element (Ce, Y, and La) modified Cu/SiO catalysts hydrolysis precipitation and impregnation method were fabricated for the vapor-phase hydrogenation of methyl acetate to ethanol. LaO showed the most pronounced promotion in the catalytic tests. After detailed characterizations, N adsorption-desorption, XRD, NO chemisorption, FTIR, H-TPR, H-TPD, TEM, XPS, and TG/DTA, we found that the addition of promoter LaO can decrease the particle size while in turn, it can increase the dispersion of copper species.

Detection of Recurrence in Retromolar Trigone using "Puffed Cheek" F-18 FDG PET-CT Scan.

Fluorine-18 Fluorodeoxyglucose positron emission tomography computed tomography (18FDG PET-CT) is routinely used for post treatment monitoring of oral cavity cancers. In addition to physiological uptake of 18FDG, apposition of anatomical structures poses a big challenge in accurate localization of pathology in oral cavity that is further complicated by surgery and/or radiotherapy related distortion. Case of recurrent Squamous Cell Carcinoma (SCC) of tongue is being presentedin a patient who underwent 18FDG PET-CT for post treatment monitoring.
