Radiologically inserted gastrostomy (RIG)
A Radiologically inserted gastrostomy (RIG), or percutaneous radiological gastrostomy (RPG), is a procedure where a gastrostomy tube is inserted percutaneously into the stomach under fluoroscopic guidance, principally to provide nutritional support for patients with swallowing disorders 1. Gastr...

Percutaneous endoscopic gastrostomy
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 via endoscopy. Alternatively a tube can be placed under radiological guidance, known as a radiologically inserted gast...
Article
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 advances with multiparametric MRI (mpMRI) of the prostate in t...
Article
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...
Article
Brachytherapy
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...
Article
Celiac plexus block
Celiac plexus block under image guidance is an easy and safe percutaneous procedure with good outcomes for pain palliation in patients who have chronic abdominal pain related to the celiac plexus.
This usually includes patients with advanced cancers, especially from upper abdominal viscera, su...
Article
Selective internal radiation therapy
Selective internal radiation therapy (SIRT), also known as transarterial radioembolization (TARE) or 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 t...
Article
Chemical ablation
Chemical ablation is a technique in which chemical ablative substances are used to cause cell death in neoplastic tissue. It is used as a standalone procedure or in combination with other techniques like TACE and radiofrequency ablation.
Agents
absolute ethanol (most commonly used)
acetic aci...
Article
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-...
Article
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 ...
Article
Hickman catheter
Hickman catheters (or Hickman lines) are a type of tunneled central venous access line.
Radiographic features
Hickman catheters are typically inserted into either jugular vein, and the proximal tubing is tunneled through the subcutaneous tissues to a skin incision on the chest. The distal part...
Article
Radioembolization
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

Article
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...

Denver shunt
A Denver shunt, or peritoneovenous shunt, is a device used to shunt ascites to the superior vena cava in patients with refractory ascites.
The proximal end is located in the peritoneal cavity and the distal end in the superior vena cava, with a subcutaneous course in the anterior chest wall. It...
