Despite considerable research evidence demonstrating significant neurobiological alterations in psychiatric disorders, incorporating neuroimaging approaches into clinical practice remains challenging. There is an urgent need for biologically validated psychiatric disease constructs that can inform diagnostic algorithms and targeted treatment development. In this article, we present a conceptual review of the most robust and impactful findings from studies that use neuroimaging methods in efforts to define distinct disease subtypes, while emphasizing cross-diagnostic and dimensional approaches. In addition, we discuss current challenges in psychoradiology and outline potential future strategies for clinically applicable translation.

Fine-needle aspiration (FNA) and core needle biopsy are the primary diagnostic modalities for assessing mass lesions. Any superficial or deep-seated lesion occurring anywhere in the body, including bone and soft tissue, can undergo this procedure to pathologically characterize it. The outcomes of FNA, performed either alone or in combination with core biopsy, are best when performed and interpreted by skilled individuals. The roles of interventional radiologists and cytologists are pivotal in ensuring adequacy of the specimen and leading the clinical team in making the diagnosis and avoiding repeat diagnostic procedures or a more invasive open surgical biopsy.

The vertebral column is the most common site of osseous metastasis, and percutaneous minimally invasive thermal ablation is becoming an important contributor to multidisciplinary treatment algorithms. Continuously evolving minimally invasive image-guided percutaneous spine thermal ablation procedures have proven safe and effective in management of selected patients with spinal metastases to achieve pain palliation and/or local tumor control. This article details the armamentarium available and the most recent advances in minimally invasive, percutaneous image-guided thermal ablation for management of spinal metastases.
