Hi,
How are you? Activity indeterminate may refer to inactive or active PTB infection. This warrants further evaluation by a doctor or additional diagnostic tests such as sputum examination. Your symptoms and medical history or presence of prior ptb diagnosis are also important. Take care and regards.
ON a CT Scan a 8x9 mm indeterminate SPN was found-rt lower lobe with dependent atelectatic changes in the lung bases. Could you explain this? Thanks.
