Case Study 3: COPD With Biologic Therapy

AGE
60
Sex
Female

INDICATIONS

  • Prior biologics therapeutic for re-current exacerbation of moderate obstructive lung disease.
  • Medication: Fasenra (benralizumab)
SUMMARY
  • SOB for further investigation.
  • At baseline CT was unremarkable. Placed on biologics for history of exacerbation.
  • Following Tx, there are functional improvements in regional ventilation indices (reduced VH and VDP). Notably, appearance of improved ventilation, specifically in the dependent areas of the right and left lungs.
  • Corresponding with patient reported improvement in symptoms.

Case Study 4: Long COVID-19 Symptoms

AGE
52
Sex
Female

INDICATIONS

  • Long COVID-19 symptoms.
SUMMARY
  • Patient hospitalised for COVID-19.
  • During hospital admission chest CT observed peripheral ground-glass and consolidative pulmonary opacities. (no XV LVAS imaging was captured)
  • Following Tx and discharge from hospital, the Pt continued to display symptoms of shortness of breath, cough and dyspnoea on exertion.
  • Following a physician consultation, the patient was referred for follow up CT and 4DMedical XV LVAS imaging.

Clinical Observations

XV LVAS:
Follow up CT observed a resolution of the peripheral ground-glass and consolidative pulmonary opacities.
XV LVAS highlighted heterogeneity between the left and right lung regional performance.
Additionally, previous areas of ground-glass and consolidative pulmonary opacities displayed under ventilation specific to that region of the lung.
Chest CT: Acute COVID-19 Infection
Structural CT: Peripheral ground-glass and consolidative pulmonary opacities
3 Months Post-acute COVID-19 Infection
Structural CT
XV LVAS
