Article Synopsis
- Radiofrequency ablation is a treatment for lung tumors that is especially useful for patients who cannot undergo surgery.
- While it's generally safe and effective, complications can arise, most of which are manageable but some may require more serious intervention.
- Radiologists are crucial for diagnosing these complications and must be knowledgeable about the imaging features seen after the procedure.
Background: Increased cardiac after load and multiple non-hemodynamic stimuli implicate in adverse left ventricular remodeling (LVR). This is particularly identifiable in treatment-resistant and secondary hypertension contexts, like primary hyperaldosteronism (PA), however little data exists on post-treatment residual LVR in these individuals.
Methods: Cardiac magnetic resonance (CMR) with T1 mapping were performed in 14 patients with treated PA matched with 15 treated patients with primary hypertension (PH) and 15 healthy individuals.
High-frequency US provides excellent visualization of superficial structures and lesions, is a preferred diagnostic modality for anatomic characterization of neck abnormalities, and has a central role in clinical decision making. Recent technological advancements have led to the development of transducers that surpass 20 MHz, elevating high-frequency US to a highly valuable diagnostic tool with broader clinical use and enabling greater spatial resolution in the assessment of skin and superficial nerves and muscles. The authors focus on evolving applications of high-frequency US in neck imaging, emphasizing practical insights and strategies in skin and neuromuscular applications.

Materials And Methods: Serial plasma samples were collected from patients receiving platinum-based chemotherapy for SCLC on the first 3 days of cycle one and on the first days of subsequent cycles with paired samples collected both before and again after infusions.
Article Synopsis
- - The study investigates discrepancies between clinical and pathological staging of pleural mesothelioma (PM) to identify features predicting whether the disease is resectable or not.
- - Researchers assessed 22 radiologic features using CT and PET/CT scans of 133 patients, classifying them as either resectable (52%) or unresectable (48%) based on several predictive indicators.
- - Key findings indicated that factors like pleural thickness and lung invasion significantly correlated with unresectability, with strong diagnostic models developed, particularly one that integrated maximum pleural thickness and mediastinal infiltration (AUC = 0.876).
