Interventional radiology studies, such as transhepatic portal venous insulin sampling (54) and selective pancreatic arterial calcium stimulation (51), have been used to localize
focal lesions.
Moreover, since state-of-the-art Doppler ultrasound is not widely available, saline infusion sonography should remain the method of choice for detecting
focal lesions in many institutions, she said.
Also,
focal lesions may make the endometrium thicker focally.
Results of Hysteroscopy and SIS are comparable in diagnosis of
focal lesions.
By USG we saw 98 cases of
focal lesions of these 27% were primary, 22% metastases, 5% were heamangiomas, 35% liver abscesses, 4% cysts and remaining 5% as hydatids (Figure-2).
A) Axial FLAIR images show two bilateral
focal lesions (arrows) in the occipital lobes with a hyperintense centre and with a mildly hypointense rim.
Bone imaging studies showed two small
focal lesions in left distal index and little fingers.
These
focal lesions revealed by SPECT/CT offer evidence of organic injury in patients whose conventional neuroimaging studies do not reveal any anatomic abnormalities (9).
Inoculation of horses with VACV-P1V (n=3) and VACV-P2V (n=3) resulted in mild and
focal lesions in four animals (two animals inoculated with each virus), characterized by papules, ulcers and mild scabs.
Magnetic resonance imaging of the brain demonstrated
focal lesions in both sides of the mastoid cavity; there was no involvement of the brain parenchyma.
7% of the patients, D & C failed to detect intrauterine disorders, especially
focal lesions of the endometrium.
The liver weighed 1600 g and was sectioned to reveal a dark red-brown, homogenous cut surface with no
focal lesions.
