REPLY: There was a remarkable silence within our community when the excellent
ventilation agent 81mKr was removed from the US market and, worse, when the extremely …

TO THE EDITOR: We refer to the recent Invited Perspective which proposes that there is now
a reduced role for V/Q scintigraphy in the detection of pulmonary embolism (PE) given the …

TO THE EDITOR: Gutte et al.(1) reported on a novel, exciting concept to diagnose
pulmonary embolism (PE) using a g-camera integrated with a multidetector CT scanner …

1035 Learning Objectives 1. To illustrate the technological & interpretive advances made in
diagnostic imaging for PE beginning from the era of CXR alone to the current times of lung …

1208 Objectives: Ventilation/perfusion (V/Q) imaging to establish likelihood of pulmonary
embolus (PE) is usually performed as a planar study. Planar imaging is limited to …

1425 Objectives: Pulmonary thromboembolism (PTE) is a serious medical condition with
high mortality if diagnosis is delayed. Ventilation-perfusion (V/Q) scintigraphy is an …

Although widely validated, current tests for pulmonary embolism (PE) diagnosis, ie
computed tomography pulmonary angiography (CTPA) and V/Q planar scintigraphy, have …

363 Objectives: A potential advantage of CTPA in the assessment of pulmonary embolism
(PE) is its ability to characterise the lung parenchyma and assess other conditions which …

ventilation-perfusion SPECT and low-dose CT: head-to-head comparison with CT …

One of the main problems encountered in the analysis of ventilation/perfusion (V/P) lung
scans for the diagnosis of pulmonary embolism (PE) is difficulty in assessing the size of the …
