Objectives: CT low-dose simulation methods have gained significant traction in protocol development, as they lack the risk of increased patient exposure. However, in-vivo validations of low-dose simulations are as uncommon as prospective low-dose image acquisition itself. Therefore, we investigated the extent to which simulated low-dose CT datasets resemble their real-dose counterparts.

- Meningiomas are the most frequently occurring primary brain tumors, often treated effectively with surgery or radiation, but recurrent and aggressive cases pose treatment challenges.
- Innovative therapies targeting somatostatin receptors, which are expressed in meningiomas, show promise, particularly through peptide radioreceptor therapy used in neuroendocrine tumors.
- Current research indicates potential for improving treatment through new drugs and tailored approaches for various meningioma types, as detailed in this review.
Objective: SPECT/CT with 99mTc-macroaggregated albumin (MAA) is generally used for diagnostic work-up prior to transarterial radioembolization (TARE) to exclude shunts and to provide additional information for treatment stratification and dose calculation. C-arm CT is used for determination of lobular vascular supply and assessment of parenchymal blood volume (PBV). Aim of this study was to correlate MAA-uptake and PBV-maps in hepatocellular carcinoma (HCC) and hepatic metastases of the colorectal carcinoma (CRC).
