Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area of Science:

  • Radiology
  • Oncology
  • Neurosurgery

Background:

  • Lumbar puncture is crucial for intrathecal chemotherapy in leptomeningeal cancer.
  • Current methods include blind or fluoroscopic guidance.
  • Limitations exist, necessitating advanced techniques.

Purpose of the Study:

  • To describe the technique of multidetector CT (MDCT)-guided lumbar puncture.
  • To evaluate the outcomes of MDCT-guided lumbar puncture for cancer patients.
  • To assess its utility for both diagnostic and therapeutic intrathecal interventions.

Main Methods:

  • Utilized multidetector CT (MDCT) for real-time imaging guidance.
  • Performed lumbar puncture targeting the thecal sac.
  • Collected data on procedural success, complications, and diagnostic/therapeutic yield.

Main Results:

  • MDCT-guided lumbar puncture demonstrated effectiveness in achieving thecal sac access.
  • The procedure was found to be safe with a low complication rate.
  • It proved particularly valuable in cases where other methods failed.

Conclusions:

  • MDCT-guided lumbar puncture is a safe and effective imaging modality.
  • It provides reliable thecal sac access for cancer patients.
  • This technique is a valuable option when standard lumbar puncture methods are unsuccessful.
