A study was conducted recently to evaluate the management approaches used by the international thoracic radiology community for small pulmonary nodules on CT.

Based on a survey of thoracic radiologists, most advise follow-up CT imaging for incidental small pulmonary nodules, with shorter follow-up for those with risk factors for malignancy.

A dedicated coronary CT protocol does not adequately depict the pulmonary arteries in order to exclude PE.

These were the findings of a recent study to assess a dedicated coronary CT protocol’s ability to evaluate for a pulmonary embolism (PE) and aortic dissection in addition to the coronary arteries.

A recent study was conducted to identify CT features that can help differentiate pure ground-glass opacities (GGOs) as bronchioloalveolar carcinoma (BAC) versus atypical adenomatous hyperplasia.

It has concluded that pure ground-glass opacity lesions are more likely to be bronchioloalveolar carcinoma if they contain internal air bronchograms, and are more likely to be atypical adenomatous hyperplasia if they are spherical in shape.

Smoothly Marginated or Attached Pulmonary Nodules Are Benign
A recent study set out to evaluate whether there are any features of solid noncalcified nodules (NCNs) seen on baseline CT that predict lung cancer.

The study was part of the Dutch-Belgian randomized lung cancer screening trial (NELSON study) and the results were published in a recent issue of Radiology.

The results seem to indicate … read more »

Prior studies have demonstrated that persistent ground-glass opacity (GGO) nodules are often bronchoalveolar cell carcinoma, atypical adenomatous hyperplasia, pulmonary lymphoproliferative disorder, or due to organizing pneumonia/fibrosis.

The objective of the study reported in Radiology was to evaluate CT features of GGO nodules with histopathologic findings. Fifty-three GGO nodules were evaluated histopathologically.

The study reported 68% of the nodules were bronchoalveolar cell carcinoma; … read more »

What are the data regarding microwave ablation of lung tumors? Does it work?

The objective of a 2008 article in Radiology was to determine the results, imaging, and safety of microwave ablation of pulmonary malignancies.

In all cases, the patients had a pulmonary malignancy that was either inoperable, or the patients refused surgical resection. Thirty patients had primary lung malignancy, and 20 … read more »

When looking at chest radiographs of the lungs, the challenge is that creating a two-dimensional representation of a three-dimensional structure is extremely problematic.

With that in mind, looking at the lung directly in cross-section without any superimposition of densities allows us to truly make distinctions with a much higher degree of reliability.

It makes sense as a first point of origin issue, … read more »
