Abstract
Design of study: Retrospective.
Objectives: To evaluate Diagnosis of Diaphragmatic paralysis in adults by the use
of M mode Ultrasound.
Setting:Department of Diagnostic Radiology, Ch. Pervaiz Elahi Institute of
Cardiology, Multan.
Results:The movement of diaphragm was noted on quiet respiration and on sniff
test showing the result of normal diaphragmatic movement in three patients,
unilateral diaphragmatic paralysis in six patients. On Chest X-ray four of
these patients with diaphragmatic paralysis had a elevated hemi-diaphragm,
because two patients were on ventilator they did not have elevated diaphragm on
chest radiography. The scanning of patients on Ultrasound was recorded in M-
mode and bilaterally on quiet respiration and on sniffing. No evidence of
movement is recorded on paralyzed side on M-mode.
Conclusion: M mode ultrasonography can be used with ease and accuracy for the
evaluation of diaphragm in the adults suspicious of diaphragmatic paralysis and
having advantage of performing more than one time and at bedside.
Equipment: GE LogiqF8 using a 2–5 MHz curved transducer.
