Percutaenous renal tumor ablation

Percutaneous ablation in the kidney is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection. It is performed via radiofrequency ablation or cryoablation. Follow-up time frame Can vary according to center but usually includes contrast-...

Percutaneous liver tumor ablation

Percutaneous liver tumor ablation techniques are well-established and effective therapeutic alternatives for the treatment of primary and secondary liver tumors. Hepatocellular carcinoma (HCC) and colorectal oligometastatic disease are the most common indications. There are specific indications ...

MRI targeted prostate biopsy

MRI targeted prostate biopsy refers to an imaging targeted technique rather than the traditional systematic approach of a prostate biopsy after respective imaging with multiparametric MRI (mpMRI) of the prostate. As a consequence of the recent advances of multiparametric MRI (mpMRI) of the pros...

Tumor ablation

Tumor ablation, or image-guided tumor ablation, is the direct application of chemical or energy-based (i.e. thermal and non-thermal) treatments to cause local tumor destruction. Techniques include: energy-based techniques thermal ablation radiofrequency ablation (RFA) microwave ablation (MWA...

Radiologically inserted gastrostomy (RIG)

Percutaneous endoscopic gastrostomy (PEG) is a procedure where a flexible feeding tube (commonly known as a PEG tube) is inserted through the abdominal wall and into the stomach. This may be placed under endoscopic or radiological guidance, in the latter, the procedure may be known as a percutan...


Radioembolization is the delivery of radioactive microspheres to cancers using an endovascular approach. It is often performed as an outpatient procedure.  Indications hepatocellular carcinoma 2 hepatic metastases from colorectal carcinoma Contraindications Absolute contraindications exces...

Selective internal radiation therapy

Selective internal radiation therapy (SIRT), also known as hepatic radioembolization, is a relatively new and developing modality for treating non-resectable liver tumors. The procedure consists of a transcatheter injection of radioactive particles via the hepatic artery.  It is generally consi...

CT guided thoracic biopsy

CT guided thoracic biopsy is usually performed for the diagnosis of suspicious lung, pleural, or mediastinal lesions. It can be performed as an outpatient procedure where patient monitoring and complications support are available.  A small percentage of lung and pleural biopsies may be performed...


Brachytherapy, also known as sealed source radiotherapy or endocurietherapy, is a form of radiotherapy where a radioactive source is placed, under the guidance of imaging, within or next to the area requiring treatment. This provides localized targeted internal radiation. Brachytherapy has been...
