Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

73
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...

Radiological Investigation I: X-ray and CT

165
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

85
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Summary

Imaging characteristics of nasal masses aid diagnosis. Computed tomography (CT), cone beam computed tomography (CBCT), and magnetic resonance imaging (MRI) help differentiate benign and malignant lesions, guiding surgical planning.

Area of Science:

  • Radiology
  • Otolaryngology
  • Pathology

Background:

  • Nasal and paranasal sinus masses present diagnostic challenges due to diverse etiologies (benign, malignant, congenital, acquired).
  • Accurate diagnosis requires integrating nasal endoscopy, advanced imaging, and histopathology.
  • Computed tomography (CT), cone beam CT (CBCT), and magnetic resonance imaging (MRI) are crucial initial and advanced diagnostic tools.

Purpose of the Study:

  • To review the imaging features of various nasal masses evaluated by CT, CBCT, and MRI.
  • To highlight imaging characteristics that assist in the differential diagnosis of sinonasal lesions.
  • To correlate imaging findings with histopathological diagnoses for improved clinical decision-making.

Main Methods:

  • Review of imaging studies (CT, CBCT, MRI) for nasal and paranasal sinus masses.
  • Analysis of key imaging features for differential diagnosis.
  • Categorization of lesions into non-neoplastic, benign/borderline tumors, and malignant tumors.

Main Results:

  • Non-neoplastic lesions include rhinoliths, inverted mesiodens, and septal mucoceles.
  • Benign/borderline tumors encompass inverted papilloma, hemangioma, and sinonasal angiofibroma.
  • Malignant tumors include adenocarcinoma, esthesioneuroblastoma, lymphoma, melanoma, and sarcoma.

Conclusions:

  • Diagnosing nasal masses is complex for otolaryngologists.
  • Imaging characteristics are vital for narrowing differential diagnoses pre-operatively.
  • Nasal endoscopy with biopsy remains the gold standard for definitive diagnosis.
